Triangular Prism Concepts and Calculations

This lesson explains how to calculate the surface area of triangular prisms. It covers the basic structure of a triangular prism, which includes two triangular bases and three rectangular faces. The lesson provides examples using an equilateral triangle and a right triangle to demonstrate the calculation of surface area. The video concludes with a summary and credits to Math Fun Academy.

What is a triangular prism composed of?

• Three triangular bases and two rectangular faces

How do you calculate the surface area of a triangular prism?

• By adding the areas of the bases and the faces

• By multiplying the areas of the bases and the faces

• By subtracting the area of the faces from the bases
