What is the maximum number of 3x3 squares that can be formed from the squares in the 6x6 checker board?
a)4 b) 6 c) 12 d) 16

Read Solution (Total 6)

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

1 2 3 4 5 6
2
3
4
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
