This section covers the methods to find volumes of common Euclidean objects.
The volume of a pyramid of height and base of area is .
The volume of a cylinder of height and radius is . (Note that this is just a special case of the formula for a prism.)
The volume of a cone of height and radius is . (Note that this is just a special case of the formula for a pyramid.)
The volume of an object defined by an upper bound of in the Cartesian three-space can be found using a triple integral: , where are the bounds of and similar bounds are defined for and .
- Centers of adjacent faces of a unit cube are joined to form a regular octahedron. What is the volume of this octahedron? (Source)
- A tripod has three legs each of length feet. When the tripod is set up, the angle between any pair of legs is equal to the angle between any other pair, and the top of the tripod is feet from the ground. In setting up the tripod, the lower 1 foot of one leg breaks off. Let be the height in feet of the top of the tripod from the ground when the broken tripod is set up. Then can be written in the form where and are positive integers and is not divisible by the square of any prime.
