2 x (8 1/2 x 11) + 2 x (8 1/2 x 2) + 2 x (2 x 11) = 265 square inches
The surface area of top and bottom faces, the surface area of two ends, and the surface area of two edges.
The surface area of every sheet in the entire bundle would be much higher. Allowing 0.004 inch for the edge area, the effective size of each sheet is 8.504 x 11.004. Multiplying this by 1000 (two sides to each sheet) we get 93578.016 square inches.

For normal caclulations you might assume the paper to be flat, giving surface area: 8.5*11*2*500=93,500
I guess if you include the width of the paper as a surface then u can get this answer:
500 sheets have width 2 inches, so each sheet has width 2/500 inches=1/250 inches. so each sheet has surface area: 2*(8.5*(1/250)+11*(1/250))+2*8.5*11=0.068+0.088+187=187.156 = X
so 500 sheets have 500*X surface area = 93,578

The bundle has 6 faces. Opposite faces have same area.
Surface area=2[8.5*11+11*2+8.5*2]
=2[93.5+22+17]=265sq in

(2 x 8.5 x 11) + (2 x 8.5 x 2) + (2 x 2 x 11)=
187 + 34 + 44 = 265 sq inches Area of bundle
500 x 2 x 8.5 x 11 = 93500 sq inches area of all pages surface area

Top and bottom faces: 2 * 8.5 * 11 = 187
2 of the side faces: 2 * 8.5 * 2 = 34
The other 2 side faces: 2 * 11 * 2 = 44
Total area: 93.5 + 17 + 22 = 265 sq in.

8.5 * 11 = 93.5 sq in (# sheets and height of stack are irrelevant to surface area calculation)

1.84 square feet, or, unreduced is 265 square inches. Peace
