We discovered that there are 204 squares on the board We found that you would add the different squares - 1 + 4 + 9 + 16+ 25 + 36 + 49 + 64.

Also in 3*3 tic tac toe board what is the total no of squares

Ans 14 ie   9+4(bigger ones)+1 (biggest one)

If you ger 100*100 board just use the formula

the formula for the sum of the first n perfect squares is

                        n x (n + 1) x (2n + 1)

                        ______________________

                                  6

if in this formula if you put n=8 you get your answer 204

for any matrix take thius formula  4*4=1^2+2^2+3^2+4^2

similarly for 8*8==1^2+2^2..........+8^2=204
