QUESTION: 10

The figure above shows a solid cube 3 inches on a side but with a 1-inch square hole cut
through it. How many square inches is the total surface area of the resulting solid figure?

A. 24
B. 42
C. 52
D. 64
E. 66

Answer(s): D
Explanation: Without the square hole, each of the cube's six outer surfaces contains 9 square
inches, for a total of 54 square inches of outer surface area. The square hole reduces that total
outer surface area by 2 square inches, to 52. Each of the four inner surfaces (inside the hole)
accounts for an additional 3 square inches, for a total of 12 square inches of inner surface
areas. The solid's total surface area is 52 + 12 = 64 square inches.
