Volume of Triangular Pyramids

In this video, Mr. J explains how to find the volume of a triangular pyramid. He introduces the formula for volume as one-third times the area of the base times the height. An example is provided, where the area of the triangular base is calculated using the formula one-half times the base times the height. The video also covers an alternative method using the area of the base times the height divided by three, showing that both methods yield the same result. The final volume is calculated and rounded to the nearest hundredth, with the result expressed in cubic inches.

What is the formula used to find the volume of a triangular pyramid?

• Area of the base plus the height

• Base times height divided by two

• One-third times the area of the base times the height

• Area of the base times height
