In
geometry, a
cuboid is a
convex polyhedron bounded by six
quadrilateral faces, whose
polyhedral graph is the same as that of a
cube. While mathematical literature refers to any such polyhedron as a cuboid, other sources use "cuboid" to refer to a shape of this type in which each of the faces is a
rectangle (and so each pair of adjacent faces meets in a
right angle); this more restrictive type of cuboid is also known as a
rectangular cuboid,
right cuboid,
rectangular box,
rectangular hexahedron,
right rectangular prism, or
rectangular parallelepiped.
