In Euclidean geometry, a parallelepiped is a three-dimensional figure (a polyhedron) having six sides (a hexahedron or prism). All six sides are parallelograms. Opposing sides are parallel and therefore all opposing sides are also congruent. Given a parallelepiped whose edges are formed by the vectors , the volume of the parallelepiped is the scalar triple product of the three vectors: File:Square pyramid.png This geometry-related article contains minimal information concerning its topic.
