8.09 Order and compare volume

Lesson

Are you ready?

Remembering how to order numbers can help us in this lesson. Let's try this problem to practice. 

Order these numbers from smallest to largest.

  1. $92,22,29$92,22,29

    $\editable{},\editable{},\editable{}$,,

  2. $516,156,561$516,156,561

    $\editable{},\editable{},\editable{}$,,

Let's see how we can use unit cubes to compare the volumes of different 3D shapes.

question 1

We want to compare the volumes of the following block stacks.

  1. Which block stack has the smaller volume?

    A

    B

    A

    B

Learn 

In this video, we see how we can compare the numbers, to work out the largest volume, as long as our shapes are using the same unit of measurement.

question 2

Select the correct symbol to compare the following two numbers:

  1. $95$95cm3 $\editable{}$ $98$98cm3

    $<$<

    A

    $>$>

    B

    $<$<

    A

    $>$>

    B

Remember!

Volume means how much space our shape takes up. If we have shapes with the same unit of measurement, we can compare the numbers, to work out the largest volume.
