A. 222 square inches
B. 111 square inches
C. 180 square inches
D. 270 square inches

1 answer

To find the surface area of a rectangular prism, you need to calculate the area of each of the six faces and then add them together.

The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh

Given:
l = 12 in
w = 3 in
h = 3 in

Surface Area = 2(12)(3) + 2(12)(3) + 2(3)(3)
Surface Area = 2(36) + 2(36) + 2(9)
Surface Area = 72 + 72 + 18
Surface Area = 162 square inches

Therefore, the correct answer is not provided in the options. The surface area of the rectangular prism is 162 square inches.
