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
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
