Solve for the surface area of the rectangular prism.
A. 270 square inches
B. 111 square inches
C. 180 square inches
D. 222 square inches

Answer 1

C. 180 square inches

To find the surface area of a rectangular prism, you need to add up the areas of all six sides.

Surface Area = 2lw + 2lh + 2wh
Surface Area = 2(12)(5) + 2(12)(3) + 2(5)(3)
Surface Area = 180

Therefore, the surface area of the rectangular prism is 180 square inches.
