If my addition is not wrong its 64+49+36+26+16+9+4+1=204 amazingly its sum of n^2 for n=1,2,3,4,5,6,7,8.... So answer is 204

1*1+1*2+1*3+...+1*8+2*1+2*2+2*3...+2*8+3*1+3*2+3*3...+8x8
(1+2+3+4+5+6+7+8)(1+2+3+4+5+6+7+8)
36*36
1296
How did you get 2080?

basically 8x8+7x7+6x6+5x5+4x4+3x3+2x2+1x1
You're right. Basically it's s^2+(s-1)^2+(s-2)^2, etc.
1+4+9+16+25+36+49+64, going by sizes. 204
