How to solve this type of puzzles without actually counting square?

You can use following formula to find out number of squares in a given puzzle.

If a puzzle has an n*n matrix of square (like above pic has 4×4). Then following formula will give correct answer.

n*(n+1)*(2n+1) / 6

So in our case we have n=4

4*(4+1)*(8+1) /6 = 30

if n was =3 then answer would have been 3*(3+1)*(6+1)/6=14

if n = 2 => 2*(2+1)*(4+1)/6=5
