Question

What is the surface area of the regular pyramid below?

Answer 1

D. 304 sq units

Surface area is just finding the area of each face of a 3d figure and adding it up together:

Area of square base:
8 • 8 = 64 sq units

Area of ONE triangle face:
1/2 • 15 • 8 = 60 sq units
MULTIPLY that by 4 because we have 4 triangle faces: 60 • 4 = 240 sq units

ADD area of square base and 4 triangle faces: 240 + 64 = 304

FINAL ANSWER OF SURFACE AREA:
304 sq. units
