VolumeThe volume of a solid body is the amount of ``space'' it occupies. Volume has units of Lengthcubed (i.e., cm3, m3, in3, etc.) For example, the volume of a box (Rectangular Parallelepiped) ofLength , Width , and Height is given by
The volume can also be computed for irregularly-shaped and curved solids such as the Cylinder andCube. The volume of a Surface of Revolution is particularly simple to compute due to its symmetry.
The following table gives volumes for some common Surfaces. Here denotesthe Radius, the height, the base Area, and, in the case of the Torus, thedistance from the torus center to the center of the tube (Beyer 1987). Surface | Volume | Cone |  | Conical Frustum |  | Cube |  | Cylinder |  | Ellipsoid |  | Oblate Spheroid |  | Prolate Spheroid |  | Pyramid |  | Pyramidal Frustum |  | Sphere |  | Spherical Cap |  | Spherical Sector |  | Spherical Segment |  | Torus |  |
Even simple Surfaces can display surprisingly counterintuitive properties. For instance, theSurface of Revolution of around the -axis for is called Gabriel's Horn, and has finitevolume, but infinite Surface Area.
The generalization of volume to Dimensions for is known as Content. See also Arc Length, Area, Content, Height, Length (Size), Surface Area,Surface of Revolution, Volume Element, Width (Size) References
