say the board is as below (6*6):

1 2 3 4 5 6

5
6

for 3*3: start from 1st row and 3rd row. Using each row we can have maximum 4, 3*3 square.
we can continue the process for (2nd and 4th row) = 4 squares, (3rd and 5th row) = 4 squares, and (4th and 6th row) = 4 squares
Total = 4+4+4+4=16 (3*3)squares
