how to find the surface area:

The surface area of the triangular prism is the sum total of the areas of its bases and its lateral faces,

debmc7
736 square feet

We have 2 triangles to add and 3 rectangles.
Area of a rectangle is length x width.
Area of a triangle is 1/2 x base x height.

The top 2 rectangular sides are 20 x 10 = 200 each = 400 total.
The bottom rectangle is 20 x 12 = 240
The triangles are each 1/2 x 12 x 8 = 48, and there are 2 triangles, = 96


Add them all up: 400 + 240 + 96 = 736 square feet
