8 x 10 = 80 inches squared (one side)
3 x 8 = 24 inches squared (one side)
3 x 10 = 30 inches squared (one side)
80 + 24 + 30 = 134 inches squared (three sides)
Double that for all 6 sides. 2 x 134 = 268 square inches.
The answer is D.

SA = 2(wl+hl+hw)

SA = 2((3)(10)+(8)(10)+(8)(3))

Multiply:

SA = 2(30 + 80 + 24)

Add:

SA = 2(134)

Multiply:

SA = 268
