General, Right and Uniform Prisms
A right prism is a prism in which the joining edges and faces are perpendicular to the base faces. This applies if the joining faces are rectangular. If the joining edges and faces are not perpendicular to the base faces, it is called an oblique prism.
Some texts may apply the term rectangular prism or square prism to both a right rectangular-sided prism and a right square-sided prism. The term uniform prism can be used for a right prism with square sides, since such prisms are in the set of uniform polyhedra.
An n-prism, having regular polygon ends and rectangular sides, approaches a cylindrical solid as n approaches infinity.
Right prisms with regular bases and equal edge lengths form one of the two infinite series of semiregular polyhedra, the other series being the antiprisms.
The dual of a right prism is a bipyramid.
A parallelepiped is a prism of which the base is a parallelogram, or equivalently a polyhedron with six faces which are all parallelograms.
A right rectangular prism is also called a cuboid, or informally a rectangular box. A right square prism is simply a square box, and may also be called a square cuboid.
An equilateral square prism is simply a cube.

Famous quotes containing the word uniform:
“We call ourselves a free nation, and yet we let ourselves be told what cabs we can and can’t take by a man at a hotel door, simply because he has a drum major’s uniform on.”
—Robert Benchley (1889–1945)
