Proving the Volume Formulas for Pyramids and Cones Using the Cavalieri Principle

This video explains how to prove the relationship between the volumes of pyramids and prisms, as well as cylinders and cones, using the Cavalieri principle. The proof involves comparing the volumes of stacked rectangular prisms to the volumes of pyramids and observing a decreasing ratio. Although the proof is not 100% perfect, it provides enough evidence to trust the volume formulas for these geometric shapes.
