Atriangular prism is 5 millimeters long and has a triangular face with a base of 3.6 millimeters and a height of 2.4 millimeters. the other two sides of the triangle are each 3 millimeters. what is the surface area of the triangular prism?

Check the picture below.

so, the prism is really just two triangles, and three rectangles.

the triangles have a base of 3.6 and a height of 2.4.

the rectangle at the bottom is a 3.6x5.

the rectangles slanted on the sides are two 3x5

so get the area of each, sum them up, and that's the area of the triangular prism.
