Question

This image shows a square pyramid.

What is the surface area of this square pyramid?


25 ft²

100 ft²

125 ft²

200 ft²

Answer 1

The surface area would be 200ft^2

Explanation:

In order to find the answer, use the formula for a square base pyramid's surface area.

SA = a^2 + 2a√a^2/4 + h^2

Now input 10 for a, which is the base edge.

And input 5√2 for h, which is the height of the pyramid.

SA = 200

Answer 2

the correct answer is D) 200 ft ^2
