Answer:

B) 37.5 cm squared!

Explanation:

First, we know that a triangular prism has 5 faces, so in order to find the surface area of this prism, we must find the area of each face, and then add them together.

Face 1 (Rectangle): 6.5 * 1.5 = 9.75

Face 2 (Rectangle): 6 * 1.5 = 9

Face 3 (Rectangle): 2.5 * 1.5 = 3.75

Face 4 (Triangle): (6 * 2.5)/2 = 6

Face 5 (Triangle): (6 * 2.5)/2 = 6

Now, we add all the areas of the faces together.

9.75 + 9 + 3.75 + 6 + 6 = 37.5

37.5 is the surface area of the whole triangular prism.
