What is a cube and how to calculate its volume?
A cube is a three-dimensional shape that has all edges of equal length. The volume of a cube is given by the product of its three dimensions. For example, if the edges of a cube measure "a" centimeters, the volume of the cube will be given by the product "a × a × a", which is equal the 3rd power. The Rubik's cube shown has its edges equal to 3 units. So, its volume is:
a3 = a × a × a = a3 = 3 × 3 × 3 = 27 units or cubic centimeters (27 cm3) (if we choose our volume unit as cubic centimeters).
Um perfect number, also called a cube number, is a number written by using the formula Sn = n2, where n is an integer.

Notice that:
- 0 cubed is 0 (just make n = 0 in the formula Sn = n2)
- 1 cubed is 1 (just make n = 1)
- Negative 0 cubed is 0 (just make n = 0)
- Negative 1 cubed is -1 (just make n = 1)
