General cuboids have many different types. When all of the rectangular cuboid's edges are equal in length, it results in a cube, with six square faces and adjacent faces meeting at right angles. [1] [3] Along with the rectangular cuboids, parallelepiped is a cuboid with six parallelogram. Rhombohedron is a cuboid with six rhombus faces.
Cuboid means "like a cube", in the sense that by adjusting the length of the edges or the angles between edges and faces, a cuboid can be transformed into a cube. In math language a cuboid is convex polyhedron , whose polyhedral graph is the same as that of a cube .
A rectangular cuboid is a convex polyhedron with six rectangle faces. These are often called "cuboids", without qualifying them as being rectangular, but a cuboid can also refer to a more general class of polyhedra, with six quadrilateral faces. [1] The dihedral angles of a rectangular cuboid are all right angles, and its opposite faces are ...
The Necker cube is an optical illusion that was first published as a rhomboid in 1832 by Swiss crystallographer Louis Albert Necker. [1] It is a simple wire-frame , two dimensional drawing of a cube with no visual cues as to its orientation , so it can be interpreted to have either the lower-left or the upper-right square as its front side.
In the case of the body cuboid, the body (space) diagonal g is irrational. For the edge cuboid, one of the edges a, b, c is irrational. The face cuboid has one of the face diagonals d, e, f irrational. The body cuboid is commonly referred to as the Euler cuboid in honor of Leonhard Euler, who discussed this type of cuboid. [15]
A cuboid is a polyhedron with six quadrilateral faces. It may also refer to: Rectangular cuboid, a cuboid with all right angles and equal opposite faces; Cuboid (computer vision), a feature used for behavior recognition in video; Cuboid, a puzzle game for the PlayStation Network; Cuboid bone, one of seven tarsal bones in the human foot

A cube, except that its faces are not squares but rhombi; Cuboid: A convex polyhedron bounded by six quadrilateral faces, whose polyhedral graph is the same as that of a cube [4] Some sources also require that each of the faces is a rectangle (so each pair of adjacent faces meets in a right angle).
