Question

What is the surface area of the square pyramid represented by the net? Enter your answer in the box. ft² An unfolded square base pyramid with sides of the base being three feet and the length from the base to the tip is five feet.

Answer 1

Start by finding the area of the base.

A = lw
A = 3 x 3
A = 9 square feet.

Sides use the formula of a triangle: 1/2bh
A = 1/2bh
A = 1/2(3)(5)
A = 1/2(15)
A = 7.5

Next, there are 4 sides, so multiply the side area by 4.
7.5 * 4 = 30 square feet.

Lastly add all surface areas together:
30 + 9 = 39 square feet.

Answer 2

Answer:

the answer should be 39
