## hexahedron

(hĕk'səhē`drən): see cubecube,
in geometry, regular solid bounded by six equal squares. All adjacent faces of a cube are perpendicular to each other; any one face of a cube may be its base. The dimensions of a cube are the lengths of the three edges which meet at any vertex.
; polyhedronpolyhedron
, closed solid bounded by plane faces; each face of a polyhedron is a polygon. A cube is a polyhedron bounded by six polygons (in this case squares) meeting at right angles.

A triangular grid, quadrilateral grid, tetrahedral grid, and hexahedral grid is a grid consisting entirely of triangles, quadrilaterals, tetrahedra and hexahedra, respectively.
The proofs of Theorems 2 and 3 break down when applied to quadrilaterals and hexahedra because, in the notation of those theorems, [E.
Combining the ideas of [9] with results given in [24, 22] yields the above estimate on quadrilaterals and hexahedra.
Obviously the above result is still valid for a 3D triangulation made of rectangular hexahedra with [RT.
