Question

Find total surface area of the pyramid.

Answer choices

A.144 inches squared

B.1150 inches squared

C.170 inches squared

D.180 inches squared

Answer 1

D) 180 inches²

SEE NOTE*

Explanation:

Base = 10x10=100

Each triangle = 1/2x10x4=20

20x4=80

100+80=180

* This may be a trick question. This pyramid CANNOT exist. If the base is 10 inches, the height of the triangles cannot be 4 inches. They must be more than 5.
