Cuboid

from Wolfram Mathworld: http://mathworld.wolfram.com/Cuboid.html

A closed box composed of three pairs of rectangular faces placed opposite each other and joined at right angles to each other, also known as a rectangular parallelepiped. The cuboid is also a right prism, a special case of the parallelepiped, and corresponds to what in everyday parlance is known as a (rectangular) "box." Cuboids are implemented in Mathematica as Cuboid[xmin, ymin, zmin, xmax, ymax, zmax] by giving the coordinates of opposite corners. The monolith with side lengths 1, 4, and 9 in the book and film version 2001: A Space Odyssey is an example of a cuboid.
