How many squares are present in a 4*4 chess board?

• jst use this formula: n*(n+1)*(2n+1)/6= 4*5*9/6=30.

• it will be 30 just use this formula 1^2+2^2+3^2+4^2=30

• n^2+(n-1)^2+.....
  squaring the number of boxes.
  here 4*4 so 4^2+3^2+2^2+1^2=30 ans.

• 30
  using 1^2 + 2^2.... +n^n

• 1×1 squares: 8×8 = 64
  2×1 squares: 7×7 = 49
  .
  .
  .
  8×8 squares: 1×1 = 1
  
  Total number of squares = 8²+7²+...+1² = 204
  
  1² + 2² + 3² + ....n² = n(n+1)(2n+1)/6
  You can prove this formula to be accurate using mathematical induction

• 30 since by formula we get 1^2 +2^2+.....+n^n here n is the no. of rows so by putting n=4 we get 30
