Cubing Numbers and Cube Roots

In this worksheet, 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
