Volume and Area of Prisms and Triangles

The video tutorial explains how to calculate the volume of a triangular prism using different methods. It starts with a basic example using given dimensions, then moves on to a right triangle example using the Pythagorean theorem. The tutorial also covers an equilateral triangle example and concludes with a complex example using Heron's formula for a triangle with three given sides. Each example demonstrates the step-by-step process of finding the area of the base and multiplying it by the height of the prism to find the volume.

What is the formula for calculating the volume of a triangular prism?

• Base times height divided by two

• Length times width times height

• Base times height of the triangle

• Area of the base times height of the prism
