Volume and Area of Cones and Pyramids

This video tutorial from Howard Community College explains how to calculate the volume of cones and pyramids. It introduces the formula for volume, which is 1/3 times the area of the base times the height, applicable to both cones and pyramids. The video provides examples of calculating the volume of a rectangular pyramid and a cone, demonstrating the use of the formula with specific measurements. The tutorial concludes with a recap of the formula and its application.
