A '''parallelepiped''' (pronounced PAH-RA-LELL-PIE-PID) is a [[geometric]] [[shape]] that one obtains from three [[orthogonal]] [[vector]]s and their sums forming a slanted box. A [[cube]] is a special case of a parallelpiped, namely where all the vectors are [[perpendicular]] to each other. The sides of the parallelepiped form [[parallel]] "pipes" (sides).
Students normally encounter parallellepipeds in [[vector calculus]], in the same introductory module that deals with [[cross product]]s and [[dot product]]s.
