Key Ideas
1Volume of a Cube. V = side^3.
2Volume of a Rectangular Prism. V = length * width * height.
3Volume of a Cylinder. V = pi * r^2 * h.
4Volume of a Sphere. V = (4/3) * pi * r^3.
5Volume of a Cone. V = (1/3) * pi * r^2 * h — exactly one-third the volume of a cylinder with the same base and height.
