Robert's Master piece

I.A.L.T. Complete Roberts master piece and figure out how much blocks it has.
(P.S There should be a pattern in the x numbers).
Here are my x numbers.

6 x 6 = 36
5 x 5 = 25
4 x 4 = 16
3 x 3 = 9
2 x 2 = 4
1 x 1 = 1

The answer is 91. Did you see the pattern? it's 1 x 1 and 6 x 6 do you see it? and here is a photo of my work and Robert's master piece.
