How many squares can be formed in a 4 * 4 grid?
A 4×4 grid will have: 16 1×1 squares; 9 2×2 squares (as there are 3 squares in each of the top 3 rows that can be an upper right hand corner of a 3×3 square), 4 3×3 squares, and 1 4×4 square. So an n x n grid will have ∑k2 total squares. In this case 16 + 9 + 4 + 1 = 30.
