Question

A package is in the shape of a triangular prism. The bases are right triangles with perpendicular legs measuring 9 centimeters and 12 centimeters. The distance between the bases is 10 centimeters.
What is the surface area of the triangular prism?

Answer 1

We compute for the surface area of the triangular prism by the adding the areas of the bases and the sides. There are two triangles and the areas will be,
                              A = 2 (1/2)(9 cm)(12 cm) = 108 cm²

There are three sides which are in rectangular shape.
                               A1 = (10)(12) = 120 cm²
                               A2 = (10)(9) = 90 cm²
                               A3 = (10)(15) = 150 cm²

The sum of these areas is 468 cm².
