right-angled hexahedron, like a cube but with edges not necessarily equal in length

A cuboid is a 3D shape. cuboids have six faces. These faces form a convex polyhedron. The faces of the cuboid can be any quadrilateral. The most common cuboids are the rectangular cuboids. They are made from 6 rectangles that are placed at right angles to each other. A cuboid that uses all square faces is a cube. The cuboid can also be called a right rectangular prism.

Properties change

The properties of a cuboid include:

  • cuboids have 12 edges
  • They have 8 corners or vertices
  • They have 6 faces.

The difference between a rectangle and a cuboid is that a rectangle is a 2D shape and a cuboid is a 3D shape.

A cube is a cuboid where all six faces have the same height and widths. Each face of a cube is a square.
