Answer:

A. 862.4 in^2

Step-by-step explanation:

1) (14x8.9)=124.6

  124.6x4(4 sides have the same surface area)=498.4

2) 13x7(half of the 14in)=91

3) Typically, to find the surface area of a right triangle, you would divide the    answer by 2, but since we have 8 right triangles, we can just multiply the 91 by 4. 91x4=364

4) 364+498.4=862.4 in^2
