An architect is designing a building that has brick walls. Whe needs to know the surface area of a brick to determine the dimensions of the wall. Find the number of square inches of one brick with a length of 8 inches, a width of 4 inches, and a height of 3 inches.
A. 136 inches
B. 136 square inches
C. 96 cubic inches
D. 32 square inches
The surface area of one brick can be calculated by finding the area of each face and adding them together.
The area of one face is 8 inches * 4 inches = 32 square inches
There are 2 faces with dimensions 8 inches * 3 inches = 24 square inches
There are 2 faces with dimensions 4 inches * 3 inches = 12 square inches
Total area = 2(32) + 2(24) + 2(12) = 64 + 48 + 24 = 136 square inches
Therefore, the answer is B. 136 square inches.
