Question

A rectangular prism is 3 meters long, 4 meters wide, and has a total surface area of 94 square meters. What is its height?


3 m
4 m
5 m
6 m

Answer 1

    S = 2lw + 3lh + 2wh
  94 = 2(3)(4) + 2(3)(h) + 2(4)(h)
  94 = 2(12) + 2(3h) + 2(4h)
  94 = 24 + 16h + 8h
  94 = 24 + 14h
- 24  - 24
  70 = 14h
   14     14
    5 = h

The answer is C.
