Demonstration: Volume of a Square Pyramid and a Prism
In this demonstration, a prism, and a square pyramid that have equal bases, and equal heights are filled with water in order to show that the volume of a pyramid is 1/3 the volume of a prism. The video shows you both mathematically, and with a demonstration, this fact.
The volume of a geometric shape is the amount of space the 3D shape occupies. It is always expressed in units cubed.
The volume formula for a prism equals the length times width times the height of the prism.
The formula is written l*w*h
The volume formula for a square pyramid equals 1/3 times length times width times the height of the pyramid.
The formula is written 1/3*l*w*h
According to the formula it takes three pyramids to fill up one prism with an equal height and base.
Watch this demonstration to see what happens when you fill up three pyramids, and pour them into a prism.
