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
