How many squares are there in a Chess board ?

When you are asking this question to any people, they immediately reply you as 64. But people forget that even the chess board is a square. In addition to that, four squares can form a square.. Like this it comes in a combination way. So, the calculation goes like this

• Number of Squares in Chess board = ( (n * (n+1) * (2n+1) ) / 6 )
• For Chess board, n=8
• Number of Squares = (8 * 9 * 17 ) / 6 = (72 * 17) / 6 = 12 * 17 =204

So, Number of Squares in Chess board = 204 Squares.
