in a 8 x 8 chess board what is the total number of squares .
ans : the total number of squares in a n x n chess board is equal to ` ` the sum of first n natural number squares ' ' i . e . , n ( n + 1 ) ( 2 n + 1 ) 6 n ( n + 1 ) ( 2 n + 1 ) 6 so substituting 8 in the above formula we get 204 answer : b
divide(multiply(multiply(8, add(8, const_1)), add(multiply(8, const_2), const_1)), subtract(8, const_2))
