To find the surface area, find the area of each side and then add them together.
The bottom is 8 x 2 = 16
The left side is 6 x 2 = 12
The slanted side is 10 x 2 = 20
The front triangle is 1/2 x 8 x 6 = 24
The back triangle is the same as the front = 24
Total surface area = 16 + 12 + 20 + 24+24 = 96 square inches.
