In geometry, a prism is a polyhedron comprising an n-sided polygonal base, a second base which is a translated reproduction (rigidly moved without rotation) of the first, and n other faces (necessarily all parallelograms) joining corresponding sides of the two bases. All cross-sections parallel to the bases are translations of the bases. Prisms are named for their bases; example: a prism with a pentagonal base is known as a pentagonal prism. The prisms are a subclass of the prismatoids.

Like many fundamental geometric terms, the word prism (Greek: πρίσμα, romanized: prisma, lit. 'one thing sawed') used to be first utilized in Euclid's Elements. Euclid defined the time period in Book XI as "a cast figure contained by way of two reverse, equal and parallel planes, while the rest are parallelograms". However, this definition has been criticized for not being particular enough relating to the nature of the bases, which caused confusion amongst later geometric writers.[2][3]

General, right and uniform prisms

A right prism is a prism in which the joining edges and faces are perpendicular to the base faces.[4] This applies if the becoming a member of faces are oblong. If the becoming a member of edges and faces aren't perpendicular to the base faces, it is called an oblique prism.

For instance a parallelepiped is an indirect prism of which the base is a parallelogram, or equivalently a polyhedron with six faces which are all parallelograms.

A truncated triangular prism with its most sensible face truncated at an indirect angle

A truncated prism is a prism with nonparallel top and bottom faces.[5]

Some texts might observe the time period rectangular prism or square prism to both a correct rectangular-sided prism and a appropriate square-sided prism. A appropriate p-gonal prism with rectangular aspects has a Schläfli image × p.

A appropriate rectangular prism is also referred to as a cuboid, or informally a rectangular box. A appropriate square prism is simply a square box, and can be referred to as a square cuboid. A appropriate rectangular prism has Schläfli symbol × × .

An n-prism, having regular polygon ends and oblong sides, approaches a cylindrical cast as n approaches infinity.

The term uniform prism or semiregular prism can be used for a correct prism with square sides, since such prisms are in the set of uniform polyhedra. A uniform p-gonal prism has a Schläfli symbol t2,p. Right prisms with steady bases and equivalent edge lengths form one of the two endless sequence of semiregular polyhedra, the different sequence being the antiprisms.

The dual of a correct prism is a bipyramid.

Volume

The volume of a prism is the product of the area of the base and the distance between the two base faces, or the peak (in the case of a non-right prism, observe that this manner the perpendicular distance).

The quantity is due to this fact:

V=Bh\displaystyle V=Bh

the place B is the base area and h is the height. The quantity of a prism whose base is an n-sided regular polygon with facet length s is subsequently:

V=n4hs2cot⁡(πn)\displaystyle V=\frac n4hs^2\cot \left(\frac \pi n\right)

Surface space

The floor space of a right prism is:

2B+Ph\displaystyle 2B+Ph

where B is the space of the base, h the top, and P the base perimeter.

The surface space of a right prism whose base is a normal n-sided polygon with side period s and top h is therefore:

A=n2s2cot⁡(πn)+nsh\displaystyle A=\frac n2s^2\cot \left(\frac \pi n\correct)+nsh

Symmetry

The symmetry staff of a appropriate n-sided prism with regular base is Dnh of order 4n, apart from in the case of a dice, which has the better symmetry crew Oh of order 48, which has three variations of D4h as subgroups. The rotation crew is Dn of order 2n, aside from in the case of a dice, which has the greater symmetry crew O of order 24, which has 3 versions of D4 as subgroups.

The symmetry crew Dnh incorporates inversion iff n is even.

The hosohedra and dihedra also possess dihedral symmetry, and a n-gonal prism can also be constructed by the use of the geometrical truncation of a n-gonal hosohedron, as well as thru the cantellation or expansion of a n-gonal dihedron.

Prismatic polytope

A prismatic polytope is a higher-dimensional generalization of a prism. An n-dimensional prismatic polytope is made from two (n − 1)-dimensional polytopes, translated into the subsequent size.

The prismatic n-polytope parts are doubled from the (n − 1)-polytope components and then growing new parts from the subsequent decrease component.

Take an n-polytope with fi i-face components (i = 0, ..., n). Its (n + 1)-polytope prism can have 2fi + fi−1 i-face parts. (With f−1 = 0, fn = 1.)

By dimension:

Take a polygon with n vertices, n edges. Its prism has 2n vertices, 3n edges, and a pair of + n faces. Take a polyhedron with v vertices, e edges, and f faces. Its prism has 2v vertices, 2e + v edges, 2f + e faces, and a pair of + f cells. Take a polychoron with v vertices, e edges, f faces and c cells. Its prism has 2v vertices, 2e + v edges, 2f + e faces, and 2c + f cells, and a pair of + c hypercells.Uniform prismatic polytope

A standard n-polytope represented by Schläfli symbol p, q, ..., t can shape a uniform prismatic (n + 1)-polytope represented by means of a Cartesian product of two Schläfli symbols: p, q, ..., t×.

By size:

A nil-polytopic prism is a line phase, represented by way of an empty Schläfli image . A 1-polytopic prism is a rectangle, made out of 2 translated line segments. It is represented as the product Schläfli image ×. If it is square, symmetry may also be diminished: × = 4. Example: Square, ×, two parallel line segments, hooked up through two line segment aspects. A polygonal prism is a three-d prism made from two translated polygons attached by means of rectangles. An ordinary polygon p can assemble a uniform n-gonal prism represented by the product p×. If p = 4, with square facets symmetry it turns into a dice: 4× = 4, 3. Example: Pentagonal prism, 5×, two parallel pentagons attached via Five rectangular aspects. A polyhedral prism is a 4-dimensional prism comprised of two translated polyhedra connected by three-d prism cells. An ordinary polyhedron p, q can construct the uniform polychoric prism, represented through the product p, q×. If the polyhedron is a cube, and the aspects are cubes, it becomes a tesseract: 4, 3× = 4, 3, 3. Example: Dodecahedral prism, 5, 3×, two parallel dodecahedra attached via 12 pentagonal prism sides. ...

Higher order prismatic polytopes also exist as cartesian products of any two polytopes. The size of a polytope is the product of the dimensions of the elements. The first example of these exist in four-dimensional space are referred to as duoprisms as the product of two polygons. Regular duoprisms are represented as p×q.

Twisted prism

A twisted prism is a nonconvex prism polyhedron built through a uniform q-prism with the side faces bisected on the square diagonal, and twisting the most sensible, generally by

π/q radians (180/q levels) in the similar path, inflicting side triangles to be concave.[6][7]

A twisted prism cannot be dissected into tetrahedra without adding new vertices. The smallest case, triangular shape, is known as a Schönhardt polyhedron.

A twisted prism is topologically similar to the antiprism, however has part the symmetry: Dn, [n,2]+, order 2n. It can be noticed as a convex antiprism, with tetrahedra got rid of between pairs of triangles.

Frustum

Pentagonal frustum

A frustum is a identical construction to a prism, with trapezoid lateral faces and other sized most sensible and backside polygons.

A celeb prism is a nonconvex polyhedron constructed by two an identical celebrity polygon faces on the most sensible and backside, being parallel and offset through a distance and attached by way of rectangular faces. A uniform big name prism could have Schläfli image p/q × , with p rectangle and a pair of p/q faces. It is topologically identical to a p-gonal prism.

A crossed prism is a nonconvex polyhedron made from a prism, where the base vertices are inverted round the middle (or circled 180°). This transforms the facet rectangular faces into crossed rectangles. For a regular polygon base, the appearance is an p-gonal hour glass, with all vertical edges passing via a unmarried middle, however no vertex is there. It is topologically just like a p-gonal prism.

A toroidal prism is a nonconvex polyhedron is like a crossed prism aside from instead of having base and most sensible polygons, easy rectangular side faces are added to near the polyhedron. This can most effective be performed for even-sided base polygons. These are topological tori, with Euler characteristic of zero. The topological polyhedral net will also be reduce from two rows of a square tiling, with vertex determine 4.4.4.4. A n-gonal toroidal prism has 2n vertices and faces, and 4n edges and is topologically self-dual.
