The bases of a rectangular prism are squares whose perimeters are 36 inches. If the height of the prism is 8 inches, what is the surface are of the prism?
The surface area of a prism consists of two parts:
1. area of the bases
2. area of the sides.
Even without knowing the dimensions of the bases, the area of the sides can be calculated if the perimeter is known:
= perimeter of base * height
= 36 inches * 8 inches
= 288 square inches.
Since the area of the bases are not known, you can only calculate the area of the sides, which is probably the answer required.
