Question

PLEASE ANSWER IF YOU CAN!!!

A square pyramid has a slant height of 7 feet. The perimeter of the base is 42 feet. Find the surface area of the pyramid. Show your work.

Answer 1

(√18.75 / 3) * 110.25

Explanation:

So if the perimeter of the base is 42, then each side is equal to 10.5

If you draw the height from the peak of the pyramid, you will have a right triangle. One of the sides is 5.5, and the hypotenuse is 7.

The height will be √18.75

The total volume is equal to the base times the height / 3

The area of the base is 110.25.

The height / 3 = √18.75 / 3

The total volume is (√18.75 / 3) * 110.25
