What is the difference between lateral surface area and total surface area?

Back

Lateral surface area includes only the sides, while total surface area includes the bases as well.

Front

If the lateral surface area of a triangular prism is 144 ft² and the height is 12 ft, what is the perimeter?

Back

Perimeter = Lateral Surface Area ÷ Height = 144 ft² ÷ 12 ft = 12 ft.
