there is a 12*6 grid..grid contains 1*1 squares..what is d total number of squares..(consider 1*1,2*2,3*3,4*4,5*5,6*6 size squares as well).

• 1*1 squares = 12*6 = 72
  2*2 squares = 11*5 = 55
  3*3 squares = 10*4 = 40
  4*4 squares = 9*3 = 27
  5*5 squares = 8*2 = 16
  6*6 squares = 7*1 = 7
  Total squares = 217

• Friends By taking 13C2 * 7C2, you are also selecting rectangles. If number of rectangles were asked ans would have been 1638. BALAKRISHNAN is right. ans will 1*1 squares = 12*6 = 72
  2*2 squares = 11*5 = 55
  3*3 squares = 10*4 = 40
  4*4 squares = 9*3 = 27
  5*5 squares = 8*2 = 16
  6*6 squares = 7*1 = 7
  Total squares = 217

• Ans: 1638
  I am Sure ...!!!

• for an M*N grid,the total no of squares will be (nm(n+1)(m+1))/4

• 12 * 6 Grid
  
  12 => 1+2+3+4+5+6+7+8+9+10 => 78
  6 => 1+2+3+4+5+6 => 21
  
  78 * 21 => 1638

• ans: 105
  for 1*1=72
  2*2=18
  3*3=8
  4*4=3
  5*5=2
  6*6=2
  5*5=2

• ANS is 217
  12*6+11*5+10*4+9*3+8*2+7*1=217

• there is no such solution for finding squares in a m*n grid, for finding squares in a grid the grid needs to be square as well
  for n*n grid no. of squares = (n*(n+1)*(2n+1))/6

• ans is 106.
  72/(1*1)=72
  72/(2*2)=18
  72/(3*3)=8
  72/(4*4)=4 with 8 as remainder(only maximum sq. POSSIBLE)
  72/(5*5)=2 with 22 as reminder...........".............
  72/(6*6)=2
  total sq.=72+18+8+4+2+2=106
