#### Worksheet Overview

Cube numbers are formed by building cubes as follows:

You can find a cubed number by multiplying the number by itself, and then by itself again.

Four cubed would be found by the following calculation:

4 x 4 x 4 = 64

You'll need to learn at least the first five cube numbers and be able to work out the others up to 10 cubed:

1 x 1 x 1 = 1

2 x 2 x 2 = 8

3 x 3 x 3 = 27

4 x 4 x 4 = 64

5 x 5 x 5 = 125

6 x 6 x 6 = 216

7 x 7 x 7 = 343

8 x 8 x 8 = 512

9 x 9 x 9 = 729

10 x 10 x 10 = 1,000

We can also write cubed numbers in a special way like this:

1 cubed = 13

2 cubed = 23

3 cubed = 33

Have a go at spotting some cubed numbers by yourself now!
