Thanks for STEM.
smallest one having dimension 11 and they will be 64
Then we have some 22 squares that will come as 49
Then we have some 33 squares that will come as 36
Then we have some 44 square that will come as 25
Then we have some 55 squares that will come as 16
Then we have some 66 squares that will come as 9
Then we have some 77 square that will come as 4
Then we have biggest88 square that will come as 1
so total will be 64+49+36+25+16+9+4+1 =204
