Cuboid

In anatomy, the cuboid bone is a bone in the end.
Cuboid

In geometry, a cuboid is a firm figure bounded by six rectangular faces: a rectangular box. All angles are right angles, and opposite faces of a cuboid are identical. It is also a correct rectangular prism. The term "rectangular or oblong prism" is
indefinite. Also the term rectangular parallelepiped is used.

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

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

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

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

Cuboid shapes are a lot used for boxes, cupboards, rooms, buildings, etc. Cuboids are among those solids that can tesselate 3-dimensional space. The shape is reasonably versatile in being able to contain several 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.
