## What is a square and how to calculate its volume?

A square is a two dimensional figure which has its two edges of equal length. The area of a square is given by the product of its two dimensions. For example, if a square has its edge length equal to ‘a’ centimeters the area of the square is given by the product "a × a" which is equal to a^{2}. The square shown has its edges equal to 4 units. So, its area is:

a^{2} = a × a × a = a^{2} = 4 × 4 × 4 = 64 units or cubic centimeters (64 cm^{2}) (if we choose our area unit as square centimeters).

A perfect square is a number that can be expressed as the product of two equal integers.

A perfect square, also called a square number, is a number written by using the formula S_{n} = n^{2}, where n is an integer.

### Notice that:

- 0 squared is 0 (just make n = 0 in the formula S
_{n}= n^{2}) - 1 squared is 1 (just make n = 1)
- Negative 0 squared is 0 (just make n = 0)
- Negative 1 squared is 1 (just make n = 1)
