A solid contained by six rhomboids; a parallelopiped.
Six sided polyhedron with each side shaped as a rhombus.
a parallelepiped bounded by six similar faces (either rhombuses or parallelograms)
a parallelepiped with congruent rhombic faces
A six-sided prism.
In geometry, a rhombohedron is a three-dimensional figure like a cube, except that its faces are not squares but rhombi. It is a special case of a parallelepiped where all edges are the same length.
