Cube Numbers (Cubes, for short)

Method / Examples

The following are cube numbers :

8	because 8 = 2 × 2 × 2	therefore 2³ (two cubed) = 8
27	because 27 = 3 × 3 × 3	therefore 3³ (three cubed) = 27
64	because 64 = 4 × 4 × 4	therefore 4³ (four cubed) = 64
1728	because 1728 = 12 × 12 × 12	therefore 12³ (twelve cubed) = 1728

To illustrate the use of the name cube:

A cube with sides of length 4 cm., will have an area of:

4 × 4 × 4 = 64 cm³ (64 cubic centimeters)
