 # 8.09 Order and compare volume

Lesson

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

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

## Learn

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

### Apply

##### 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.

## Apply

##### 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.
