Question

Find the total surface area of the square pyramid in the figure.

Question 8 options:

A)

64 yd.^2

B)

224 yd.^2

C)

112 yd.^2

D)

144 yd.^2

Answer 1

D

Explanation:

Surface area is area of base plus all 4 sides. Base is a square with s = 8 so area is 64sq yd. Sides are triangles, with A = 1/2 bh, so 1/2(8)(5) = 20. Four sides would be 80sq yds. Add base and sum is 144 sq yds.
