What is the surface area of the regular pyramid below?
1 answer:
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 BRAINLIEST will be much appreciated! -SpaceMarsh, have a nice day/night!
