In the next section we elaborate on what is 8 squared and there you can also find our calculator.

What is 8 Squared?

A square is a flat shape with four equal sides; every angle is 90°.

Hence, a square with side length 8 has an area of 64.

8 squared equals the sum of the first 8 odd numbers:


In addition, the number can be calculated from 7 squared using the following identity:

n2 = (n − 1)2 + (n − 1) + n = (n − 1)2 + (2n − 1)
(8)2 = 72 + 7 + 8 = 72 + 15 = 64

It can be also be computed from 7 squared with this identity:

n2 = 2 x (n − 1)2 − (n − 2)2 + 2
(8)2 = 2 x 72 – 62 + 2 = 2 x 49 – 36 + 2 = 64

The difference between the perfect square of 8 and its predecessor, 7, can be calculated with the identity n2 − (n − 1)2 = 2n − 1:

2 x 8 – 1 = 15 = (8)2 – 72 = 64 – 49 = 15

8 is even, and the square numbers of even numbers are also even: (2n)2 = 4n2.

Squares of even numbers like 8 are divisible by 4 for


= n2.
