#### Worksheet Overview

In this activity, we will learn how to estimate cube numbers and cube roots.

To cube a number we multiply it by itself three times:

43 = 4 x 4 x 4 = 64

It can be illustrated as a cube made up of smaller cubelets - 4 long, 4 wide and 4 high.

There are 64 cubelets in this cube.

The cube root of a number is the inverse of a cube.

The cube root of 8 is 2, because 2 × 2 × 2 = 8.

We write 3√8 = 2

We can use a calculator to work out tricky cubes and cube roots, but it is important to know by heart all the cube and cube roots of numbers up to 10.
