Question

The figure is a triangular prism with equilateral triangle bases.
Find the surface area of each prism.

A triangular prism has right triangle bases with vertical legs measuring 6 meters, horizontal legs measuring 8 meters, and a hypotenuse measuring 10 meters. The rectangular bases have a length measuring 9 meters.
A rectangular prism has a front base with a length measuring 4 inches. Its faces have a length measuring 5 inches and a width measuring 6 inches.
A rectangular prism has a front base with a length measuring 7 meters. Its faces have a length measuring 4 meters and a height measuring 6 meters.

Answer 1

Triangular Prism:
Surface Area = (6 + 8 + 10) * 9 + 3 * (6 * 8) = 189 m^2

Rectangular Prism (1):
Surface Area = 4 * (5 * 6) + 2 * (5 * 4 + 6 * 4) = 160 in^2

Rectangular Prism (2):
Surface Area = 7 * (4 * 6) + 2 * (4 * 7 + 6 * 7) = 294 m^2
