The cube is also a square parallelepiped, an equilateral cuboid and a right rhombohedron. A three-dimensional "orthotope" is also called a right rectangular prism, rectangular cuboid, or rectangular parallelepiped. The fibula articulates with the calcaneum, and the astragalus articulates with the cuboid bone. The tibialis posterior inserts to the under surface of the cuboid bone. Now suppose that there is a perfect dissection of a rectangular cuboid in cubes. Triangular valves in the fruit will open, dispersing yellow, cuboid seeds. A right rectangular prism is also called a "cuboid", or informally a "rectangular box". The pre-formed fragmentation may be spherical, cuboid, wire or notched wire. The only furniture consisted of a hundred little black cuboid moveable stools. The Face cuboid has just one of the face diagonals irrational. A perfect cuboid is an Euler brick whose space diagonal is also an integer. This is the Euclidean analog of "boosting" a cuboid in E. The "Kaaba" is a cuboid stone structure made of granite. In the case of the Body cuboid, the body (space) diagonal is irrational. E-1027 is a white cuboid built on rocky land on raised on pillars.
