Hexahedron
a figure having six faces, or a solid bounded by six planes.
The term cube is now generally applied to the regular hexahedron.
HEXAMETER (-am'e-tur), the heroic verse of the Greeks and Romans. As its name implies, it consists of six feet, properly dactyls, the last of which is shortened by one syllable, and so becomes a trochee, or, as the final syllable is long by position, a spondee.
