To quickly calculate the number of squares in a grid, you can use the formula n(n+1)(2n+1)/6, where n is the number of rows or columns in the grid. This formula works by first calculating the sum of the squares of the first n natural numbers (1, 2, 3, ..., n), and then dividing that sum by 6 to find the total number of squares in the grid. For example, if the grid has 4 rows and 4 columns, the formula would be 4(4+1)(24+1)/6 = 45*9/6 = 100/6 = 16 squares.
