What is 256 Squared?

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

Hence, a square with side length 256 has an area of 65,536.

256 squared equals the sum of the first 256 odd numbers:

In addition, the number can be calculated from 255 squared using the following identity:

n² = (n − 1)² + (n − 1) + n = (n − 1)² + (2n − 1)
(256)² = 255² + 255 + 256 = 255² + 511 = 65,536

It can be also be computed from 255 squared with this identity:

n² = 2 x (n − 1)² − (n − 2)² + 2
(256)² = 2 x 255² – 254² + 2 = 2 x 65025 – 64516 + 2 = 65,536

The difference between the perfect square of 256 and its predecessor, 255, can be calculated with the identity n² − (n − 1)² = 2n − 1:

2 x 256 – 1 = 511 = (256)² – 255² = 65,536 – 65025 = 511

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

Squares of even numbers like 256 are divisible by 4 for

= n².
