Question

The area of the base of a prism is 55 mm2. The perimeter of the base is 30 mm. The height of the prism is 7 mm.

What is the surface area of the prism?

A.
445 mm2

B.
320 mm2

C.
265 mm2

D.
92 mm2

Answer 1

Bottom area = 55
Top area will be the same as the bottom. Therefore, 55
Lateral or side surface area = perimeter of base * height = 30 * 7 = 210

Total surface area = 210 + 55 + 55
