2. Parallelepiped - Wikipedia

   en.wikipedia.org/wiki/Parallelepiped

   In geometry, a parallelepiped is a three-dimensional figure formed by six parallelograms (the term rhomboid is also sometimes used with this meaning). By analogy, it relates to a parallelogram just as a cube relates to a square. [ a] Three equivalent definitions of parallelepiped are. a hexahedron with three pairs of parallel faces, a ...

3. Frustum - Wikipedia

   en.wikipedia.org/wiki/Frustum

   Frustum. In geometry, a frustum ( Latin for 'morsel'); [ a] ( pl.: frusta or frustums) is the portion of a solid (normally a pyramid or a cone) that lies between two parallel planes cutting the solid. In the case of a pyramid, the base faces are polygonal and the side faces are trapezoidal. A right frustum is a right pyramid or a right cone ...

4. Packing problems - Wikipedia

   en.wikipedia.org/wiki/Packing_problems

   v. t. e. Packing problems are a class of optimization problems in mathematics that involve attempting to pack objects together into containers. The goal is to either pack a single container as densely as possible or pack all objects using as few containers as possible. Many of these problems can be related to real-life packaging, storage and ...

5. Prism (geometry) - Wikipedia

   en.wikipedia.org/wiki/Prism_(geometry)

   Prism (geometry) In geometry, a prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy (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.

6. Wedge (geometry) - Wikipedia

   en.wikipedia.org/wiki/Wedge_(geometry)

   A wedge is a polyhedron of a rectangular base, with the faces are two isosceles triangles and two trapezoids that meet at the top of an edge. [1]. A prismatoid is defined as a polyhedron where its vertices lie on two parallel planes, with its lateral faces are triangles, trapezoids, and parallelograms; [2] the wedge is an example of prismatoid because of its top edge is parallel to the ...

7. Trapezohedron - Wikipedia

   en.wikipedia.org/wiki/Trapezohedron

   Trapezohedron. In geometry, an n-gonal trapezohedron, n-trapezohedron, n-antidipyramid, n-antibipyramid, or n-deltohedron[ 3],[ 4] is the dual polyhedron of an n-gonal antiprism. The 2n faces of an n-trapezohedron are congruent and symmetrically staggered; they are called twisted kites. With a higher symmetry, its 2n faces are kites (sometimes ...

8. Trapezoid - Wikipedia

   en.wikipedia.org/wiki/Trapezoid

   Look up trapezoid in Wiktionary, the free dictionary. In geometry, a trapezoid ( / ˈtræpəzɔɪd /) in North American English, or trapezium ( / trəˈpiːziəm /) in British English, [ 1][ 2] is a quadrilateral that has one pair of parallel sides. The parallel sides are called the bases of the trapezoid. The other two sides are called the ...

9. Prismatoid - Wikipedia

   en.wikipedia.org/wiki/Prismatoid

   Prismatoid. In geometry, a prismatoid is a polyhedron whose vertices all lie in two parallel planes. Its lateral faces can be trapezoids or triangles. [ 1] If both planes have the same number of vertices, and the lateral faces are either parallelograms or trapezoids, it is called a prismoid. [ 2]
