  2. Prism (geometry) - Wikipedia

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

    A right rectangular prism (with a rectangular base) is also called a cuboid, or informally a rectangular box. A right rectangular prism has Schläfli symbol { }×{ }×{ }. A right square prism (with a square base) is also called a square cuboid, or informally a square box. Note: some texts may apply the term rectangular prism or square prism to ...

  3. Rectangular cuboid - Wikipedia

    en.wikipedia.org/wiki/Rectangular_cuboid

    By definition, this makes it a right rectangular prism. Rectangular cuboids may be referred to colloquially as "boxes" (after the physical object). If two opposite faces become squares, the resulting one may obtain another special case of rectangular prism, known as square rectangular cuboid. [b] They can be represented as the prism graph.

    Prism: +, where B is the area of a base, P is the perimeter of a base, and h is the height of the prism. pyramid : B + P L 2 {\displaystyle B+{\frac {PL}{2}}} , where B is the area of the base, P is the perimeter of the base, and L is the length of the slant.

  5. Parallelepiped - Wikipedia

    en.wikipedia.org/wiki/Parallelepiped

    a prism of which the base is a parallelogram. The rectangular cuboid (six rectangular faces), cube (six square faces), and the rhombohedron (six rhombus faces) are all special cases of parallelepiped.

    Quarter-circular area [2] ... Right-rectangular pyramid: a, b = the sides of the base ... b = the base side of the prism's triangular base,

  7. Cuboid - Wikipedia

    en.wikipedia.org/wiki/Cuboid

    [1] [3] Along with the rectangular cuboids, parallelepiped is a cuboid with six parallelogram. Rhombohedron is a cuboid with six rhombus faces. A square frustum is a frustum with a square base, but the rest of its faces are quadrilaterals; the square frustum is formed by truncating the apex of a square pyramid.
