Let x be the number of 52 cent stamps that Sally has and let y be the number of 34 cent stamps that she has.
Then,
52x + 34y = 1150 --- (1)
Also, she has six more 34 cent stamps than 52 cent stamps.
Therefore, y = x + 6
(1) becomes
52x + 34(x + 6) = 1150
52x + 34x + 204 = 1150
86x + 204 = 1150
86x = 1150 - 204
86x = 946
x = 11
and y = 11 + 6 = 17
Hence, Sally has eleven 52 cent stamps and seventeen 34 cent stamps.

The surface area of a rectangular prism is always:
A=2(xy+xz+yz), where x, y, and z are the three dimensions of the prism.
A=2(50*90+50*3.5+90*3.5)
A=2(4500+175+315)
A=2(4990)
A=9980 mm^2
