Paul cut a wedge of cheese in the shape of a triangular prism. The diagram shows the dimensions of the cheese section. Paul wraps the cheese in plastic wrap to store it in the refrigerator in his deli. What is the total surface area of the cheese surface to be wrapped, assuming no overlap? 32.65625 in.2 64.625 in.2 76.5 in.2 88.375 in.2

.

Step-by-step explanation:

The triangular prism shown in the diagram has five faces:

Note that the two triangular faces at the top and bottom are identical. (In other words, these two triangles are congruent, with the same shape and area.)

From the numbers near the triangle at the top of this prism, each of the two triangles has a height of on a base of length . The area of each of these triangles would be:

.

There are two such triangular faces in this prism. When combined, these two faces will contribute an area of to the surface area of this prism.

There are three rectangular faces on the sides of this triangular prism. They have different lengths but share the same width:

The area of these three rectangles, combined. will be:

.

Combine the surface area of the five faces to obtain the surface area of this triangular prism:
