Rectangular prism: 12 in, 5 in, 3 in
Solve for the surface area of the rectangular prism.
a. 180 square inches
b. 111 square inches
c. 222 square inches
d. 270 square inches
The formula to find the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l, w, and h are the length, width, and height of the prism respectively.
Plugging in the values:
l = 12 in
w = 5 in
h = 3 in
Surface area = 2(12)(5) + 2(12)(3) + 2(5)(3)
Surface area = 120 + 72 + 30
Surface area = 222 square inches
Therefore, the correct answer is:
c. 222 square inches
