BTW....my best time is under one minute! You can beat me!
The trick to getting these types of speed distance time calculations is to think of the times used as fractions, and then apply the time formula (time = distance/speed).
Other questions can be solved using basic logic. To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU

This video shows a step by step procedure to finding volume of a rectangular prism.
We use the formula volume = length x width x height.
Notice because we use 3 measurements when we work out the volume of a 3D shape we end with an answer in cubic units (units^3).
We then look out how to work out the volume of composite objects - that is the volume of objects containing more than one shape.
This video has a particular focus to real world use of volume and uses measurement concepts. To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU

How Many Faces, Edges And Vertices Does A Cube Have?
Here we’ll look at how to work out the faces, edges and vertices of a cube.
We’ll start by counting the faces, these are the flat surfaces that make the cube. A cube has 6 faces altogether - all square in shape.
Next we’ll work out how many edges the cube has, which are where two faces meet. A cube has 12 edges.
Next we’ll count the corners of the cube (the corners). Do that and you'll get 8.
For the full playlist for the faces, edges and Vertices of a whole lot of 3D shapes go to https://www.youtube.com/playli....st?list=PLjbxBzUM6SL

What Do You Do With an Idea
by Kobi Yamada
Illustrated by Mae Besom
Read by Let's Read Stories
A New York Times Best Seller and award-winning book, What Do You Do With an Idea? is for anyone who's ever had a big idea.
This is the story of one brilliant idea and the child who helps to bring it into the world. As the child's confidence grows, so does the idea itself. And then, one day, something amazing happens. This is a story for anyone, at any age, who's ever had an idea that seemed a little too big, too odd, too difficult. It's a story to inspire you to welcome that idea, to give it some space to grow, and to see what happens next. Because your idea isn't going anywhere. In fact, it's just getting started.
Praise for What Do You Do With an Idea?
National best seller, appearing in the New York Times, Wall Street Journal, USA Today, and Publishers Weekly.

"Despite the fact that it's Yamada's first time writing a children's book, it's had breakout success, selling over 300,000 copies since its publication date of January 2014."—Publisher's Weekly

In eastern Europe, in the 17th century a couple of "great powers" were coming into their own. The vast empire of Russia was modernizing under Peter the Great, and the relatively tiny state of Prussia was evolving as well. Russia (and Tsar Peter) reformed many aspects of Russian governance, realigning them toward the way things were done in western Europe. In Prussia, efficiency of institutions became a thing, and Prussia turned into "a large army with a small state attached."

Active galaxies pour out lots of energy, due to their central supermassive black holes gobbling down matter. Galaxies tend not to be loners but instead exist in smaller groups and larger clusters. Our Milky Way is part of the Local Group, and will one day collide with the Andromeda galaxy. Clusters of galaxies also clump together to form superclusters, the largest structures in the Universe. In total, there are hundreds of billions of galaxies in the Universe.

From 1932 to 1972, the United States Public Health Service and the Centers for Disease Control and Prevention operated an extremely unethical medical experiment on the effects of outcomes of untreated syphilis. Hundreds of poor Black men from Macon County, Alabama were enrolled in the study, and treatment for syphilis was withheld from them. Even after antibiotics became available that could cure syphilis, these men were left to suffer from the disease and expose their families to syphilis as well. Today we're learning about the Tuskegee Syphilis Experiment, a shameful example of racism in American medicine, and a tragedy that still impacts how many Black Americans think about healthcare today.

The Milky Way is our neighborhood in the universe. It’s a galaxy and there are many others out there. Galaxies contain gas, dust, and billions of stars or more. They come in four main shapes: elliptical, spiral, peculiar, and irregular. Galaxies can collide, and grow in size by eating each other.

Your heart gets a lot of attention from poets, songwriters, and storytellers, but today Hank's gonna tell you how it really works. The heart’s ventricles, atria, and valves create a pump that maintains both high and low pressure to circulate blood from the heart to the body through your arteries and bring it back to the heart through your veins. You'll also learn what your blood pressure measurements mean when we talk about systolic and diastolic blood pressure.

In which John Green teaches you about the Cold War as it unfolded in Asia. As John pointed out last week, the Cold War was occasionally hot, and a lot of that heat was generated in Asia. This is starting to sound weird with the hot/cold thing, so let's just say that the United States' struggle against communist expansion escalated to a full-blown, boots-on-the-ground war in Korea and Vietnam. In both of these cases, the United States sent soldiers to intervene in civil wars that it looked like communists might win. That's a bit of a simplification, but John will explain it all to you.

The Renaissance was a cultural revitalization that spread across Europe, and had repercussions across the globe, but one smallish city-state in Italy was in many ways the epicenter of the thing. Florence, or as Italians might say, Firenze, was the home to a seemingly inordinate amount of the art, architecture, literature, and cultural output of the Renaissance. Artists like Michelangelo, Leonardo daVinci, Sandro Boticelli, and many others were associated with the city, and the money of patrons like the Medici family made a lot of the art possible. Today you'll learn about how the Renaissance came to be, and what impact it had on Europe and the world.

In which John Green talks about the many revolutions of Latin America in the 19th century. At the beginning of the 1800s, Latin America was firmly under the control of Spain and Portugal. The revolutionary zeal that had recently created the United States and had taken off Louis XVI's head in France arrived in South America, and a racially diverse group of people who felt more South American than European took over. John covers the soft revolution of Brazil, in which Prince Pedro boldly seized power from his father, but promised to give it back if King João ever returned to Brazil. He also covers the decidedly more violent revolutions in Mexico, Venezuela, and Argentina. Watch the video to see Simón Bolívar's dream of a United South America crushed, even as he manages to liberate a bunch of countries and get two currencies and about a thousand schools and parks named after him.

Today, we're going to talk about how the Earth moves, but to do that, we're going to have to go way back to the early days of the galaxy! Processes that happened before the Earth even formed have led us to the geographic patterns and processes that create Earth's environments and support all living things. We'll talk about how the Earth rotates, the effects of it being slightly tilted, how events like sea ice melting impact how the Earth wobbles, and of course talk about how our elliptical orbit gives us seasons. So many of our life decisions are influenced by the motion of Earth. It guides where we decide to live, what food we eat, or even what weather we experience - which we'll talk about more next time.

In which John Green teaches you about the fall of the Roman Empire, which happened considerably later than you may have been told. While the Western Roman Empire fell to barbarians in 476 CE, the Byzantines in Constantinople continued the Eastern Empire nicely, calling themselves Romans for a further 1000 years. Find out what Justinian and the rest of the Byzantine emperors were up to over there, and how the Roman Empire dragged out its famous Decline well into medieval times. In addition to all this, you'll learn about ancient sports riots and hipster barbarians, too.
Chapters:
Introduction: The Fall of Rome 00:00
Why Did the Roman Empire Fall? Barbarians at the Gates 0:30
Why Did the Roman Empire Fall? Barbarians Inside the Gates 2:07
An Open Letter to Pants 4:10
Constantine and the Eastern Roman (Byzantine) Empire 5:10
Comparing the Eastern & Western Roman Empires 6:57
Emperor Justinian 8:08
The Orthodox and Catholic Churches Split 10:38

In which John Green teaches you about one of the least funny subjects in history: slavery. John investigates when and where slavery originated, how it changed over the centuries, and how Europeans and colonists in the Americas arrived at the idea that people could own other people based on skin color.
Slavery has existed as long as humans have had civilization, but the Atlantic Slave Trade was the height, or depth, of dehumanizing, brutal, chattel slavery. American slavery ended less than 150 years ago. In some parts of the world, it is still going on. So how do we reconcile that with modern life? In a desperate attempt at comic relief, Boba Fett makes an appearance.

In the late 19th and early 20th centuries, Black American Women were struggling with both racism and misogyny as they fought for their rights. Black Women formed clubs and organized to make sure civil and political rights were extended to ALL Black people, not just Black men. These clubs were grass-roots organizations of middle-class women who were often only one generation removed from slavery. Today we'll learn about the origins of these clubs and some of the notable women who drove this movement.

Much like a cell membrane, our atmosphere forms a protective boundary between outer space and the biosphere that allows for all life to exist on Earth’s surface. Today, we’re going to talk about its composition and layers (the troposphere, stratosphere, mesosphere, and thermosphere), follow the path of a sunbeam of light as it travels through space and (potentially) reaches Earth’s surface, and discuss how the greenhouse effect can be both a good and bad thing!
