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

Dividing by multiples of 10 is simple to do.
First count the number of zeros in the number you are dividing by, then move the decimal place of the number being divided the same number of times.
Because we are dividing by numbers ten and above the answer is going to be smaller, and so the decimal place moves to the left. 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
