A generalized form of a cube. volume = length × width × height

Points at a fixed distance from a given straight line axis. volume = πr2h

A cube is the three-dimensional analog of a square. volume = a3

Enter the length, width and depth of your pond to figure out how much water it holds. volume = length × width × height

A cone is a three-dimensional shape that tapers smoothly from its typically circular base to a common point called the apex (or vertex) V=πr2(h/3)

A sphere is the three-dimensional counterpart of the two-dimensional circle. volume = (4/3)πr3
