###### Question:

Cho is building a sandcastle in the shape of a triangular pyramid. the area of the base is 7 square feet. each side of the base has a length of 4 feet and the height of each face is 2 feet. what is the surface area of the pyramid

## Answers

Find the area of one of the triangular sides, so 4×2=8. multiply that by 3 because there are three triangular sides in a triangular pyramid, so 8×3=24.

add that with the area of the base, so 7+24=31

The surface area of the pyramid is 23 square feet.
