Volume of Pyramids and Prisms, Cones and Cylinders

One of my former students once asked me, "Sir, how do you memorize all these math formulas we are studying?"
I told him I do not memorize them. I just learned how to derive one from the other. For example, if I can remember the formula for the area of a circle, I can easily remember the formula for the volume of a cylinder, and if I can deduce the formula for a cylinder, then I can "derive" the formula for the volume of a cone because they are all connected. I focus more on the interconnection of concepts and the corresponding real-world interpretations if there is any,  rather than randomly memorizing the individual formula.
In this video, we are going to use rice, paper patterns, and solid figures to explore the interconnectedness of some math formulas, particularly that of the volume of prisms and pyramids, cylinders and cones
