Best answer gets to be !

use a net to find the surface area of the prism.

a. 315 in.2

b. 784 in.2

c. 469 in.2

d. 539 in.2

  C. 469 in²

Step-by-step explanation:

The net of the object is a rectangle that is 28 inches long and 14 inches wide. Its area is 392 square inches.

In addition, there are two triangles with base 11 inches and height 7 inches. Together, they have the area of a rectangle 7 by 11, or 77 square inches.

The total surface area of the prism is then ...

  (392 + 77) in² = 469 in²

_____

The area of a rectangle is the product of its length and width.

The area of a triangle is half the product of its base and height. So, the area of two identical triangles is the product of their base and height.

_____

Comment on the geometry

This geometry cannot exist as shown. The height of the triangular face is closer to 6.454 inches than to 7 inches.
