In a triangular prism, the front and back faces are triangles and the other faces are rectangles. In the front face, the base has length 10 inches.

  1. Surely you know how to find the area of a triangle or a rectangle. The prism has two triangular faces. Each has
    base=10 and height 8.7

    The prism has three long rectangular faces. Each has
    length=12 and height=10

    So, what do you get?
