# Extensive Definition

- In anatomy, the cuboid bone is a bone in the foot.

The square cuboid, square box ,or right square
prism (also ambiguously called square prism) is a special case of
the cuboid in which at least two faces are squares. The cube is a
special case of the square prism in which all faces are
squares.

If the dimensions of a cuboid are a, b and c,
then its volume is abc
and its surface area
is 2ab + 2bc + 2ac''.

The length of the space
diagonal is d = \sqrt .

It is a convex
polyhedron. It
contains faces that enclose a single region of space. It has 6
faces, 8
vertices,
and 12 edges.

Euler's
formula (the number of faces (F), vertices (V), and edges (E)
of a polyhedron are related by the formula F + V = E + 2 gives here
6 + 8 = 12 + 2.

Cuboid shapes are often used for boxes, cupboards, rooms,
buildings, etc. Cuboids are among those solids that can tesselate
3-dimensional space. The shape is fairly versatile in being
able to contain multiple smaller cuboids, e.g. sugar cubes in a box, small boxes
in a large box, a cupboard in a room, and rooms in a
building.
