What is the surface area of this regular pyramid?

A. 230 in

B. 304 in

C. 480 in

D. 544 in

Answer: option b

Step by step explanation; surface area is the value that expresses the amount of area you can touch on a figure

Since there's four triangular faces, you do 4 * (1/2*8*15)

Since there's one square face, you do (8*8)

Together, you expression is (8 * 8) + 4 * (1/2 * 8 * 15)

Which is 394
