Find the surface area of the
square pyramid below:
14.5 m
7.5 m

Answer 1

Total surface area = 512.758

Answer 2

Answer: 427.75 square meters

Explanation:

The area of the square base is (14.5)(14.5) = 210.25 square meters.

The area of each triangular face is (7.5)(14.5)/2 = 54.375 square meters.

So, the total surface area is 4(54.375)+210.25 = 427.75 square meters.
