What is the surface area of this regular pyramid?
A. 230 in
B. 304 in
C. 480 in
D. 544 in

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
