I can make it slimier by using Faulhaber's formula

First Proof

Second Proof

(On the LHS, all the terms will get cancelled (Except (n+1) and 1))

Third Proof

The equivalence between the sum of squares and the cubic polynomial may also be shown by a double counting proof in which one counts in two different ways the number of ways to choose three numbers x, y, and z from the set {1, 2, 3, ... n + 1}, in such a way that z > x and z > y.

First, we fix z and consider the number of ways of choosing x and y. If z = 1 then there are no values of x and y that satisfy the inequality, if z = 2 then the only possible choice is x = y = 1, if z = 3 then x and y may independently be chosen to be either 1 or 2, and in general once z is chosen there are (z − 1)2 ways of choosing x and y. Hence the total number of ways of choosing x, y, and z is.

4 squares in a 2 by 2 grid 9 squares in a 3 by 3 grid 16 squares in a 4 by 4 grid 25 squares in a 5 by 5 grid 36 squares in a 6 by 6 grid 49 squares in a 7by 7 grid 64 squares in a 8 by 8 grid 81 squares in a 9 by 9 grid 100 squares in a 10 by 10 grid

Actually, there is more than 81 squares. SQUARE SIZES Multiplication to do: 1x1=81 ---> 9x9 2x2=64 ---> 8x8 3x3=49 ---> 7x7 4x4=36 ---> 6x6 5x5=25 ---> 5x5 6x6=16 ---> 4x4 7x7=9 ---> 3x3 8x8=4 ---> 2x2 9x9=1 ---> 1x1 now add up all products or amount of squares for each size.....and you get? 285!!! there are 285 squares inn a 9x9 grid.

The answer depends on the grid.

There are 4 squares in a 2 x 2 grid.

12 squares.
