Question

Bradley made a house for his dog, Bowser, out of wood with a cube base and a triangular prism top. The dimensions of the dog house are a = 4 feet, b = 1 foot, and c = 2.2 feet.

If Bradley plans to paint the outside of the dog house blue, not including the bottom, how many square feet of paint will he use?


A. 101.6 square feet

B. 85.6 square feet
.
C. 117.6 square feet

Answer 1

The answer to your problem is, 23.6 or 49.8

Explanation:

Surface area of cube=4 x a²----> 4 x 2²-----> 16 ft²

Surface area of triangular prism=2*[a*c]+2*[a*b/2]---> 2*[2*1.4]+[2*1]

Surface area of triangular prism=5.6+2----> 7.6 ft²

Surface area of the figure=16 ft²+7.6 ft²----> 23.6 ft²

Thus the answer to your problem is, 23.6 or 49.8

It could be either one did the same quiz but I had different answers every time so choose which one you have :).
