To find the number of axa squares on a chess board a formula of (9- a)^2 can be used. For eg: the number of 1x1 squares will be (9-1)^2 = 64 the number of 2x2 squares will be (9-2)^2 = 49 and so on... the total number of squares in a chess board will be n^2 upto 8 = 204 The total number of rectangles in a chess board will be n^3 upto 8 = 1296 Please correct me if I am wrong.

For eg: the number of 1x1 squares will be (9-1)^2 = 64the number of 2x2 squares will be (9-2)^2 = 49and so on...

the total number of squares in a chess board will be n^2 upto 8 = 204

The total number of rectangles in a chess board will be n^3 upto 8 = 1296

Please correct me if I am wrong.
