There are many different sized squares on a chessboard. The smallest squares are in an 8x8 grid, so we have 64 small squares. There are 7x7 2x2 squares, so we have 49 2x2 squares There are 6x6 3x3 squares, so we have 36 3x3 squares There are 5x5 4x4 squares, so we have 25 4x4 squares There are 4x4 5x5 squares, so we have 16 5x5 squares There are 3x3 6x6 squares, so we have 9 6x6 squares There are 2x2 7x7 squares, so we have 4 7x7 squares And there's the one big square that's the chessboard. All this adds up to 204 squares.

16 Answer #2 It is 16 if you just count the 1 x 1 squares but the 16 squares also form a 4x4 square. There are also 2x2 squares and 3x3 squares in the pattern. 16 1x1 squares 9 2x2 squares 4 3x3 squares 1 4x4 square 30 squares (possibly more?)
Non-prime squares
There 64 1x1 squares on a chessboard. There are also 49 2x2 squares, 36 3x3 squares, 25 4x4, 16 5x5, 9 6x6, 4 7x7 and 1 8x8. Total number of squares on a chessboard is therefore 204.
Just calculate the square numbers: 1x1, 2x2, 3x3, 4x4, etc., until you get a square that is larger than 130.
