The 3rd dimension, space, has length, width, and height. It is also sometimes referred to as the realm, which represents a three-dimensional space of infinite extent. Points in space can be described with three coordinates, written in the form .
Polyhedra
Main Article: List of Polyhedra By Type
The platonic solids have all their faces be the same type, all their edges be the same length, and all vertices have the same number of edges coming from them, and are convex. They are sometimes associated with the classical elements.
All platonic solids can also be used as dice, with the number of possible values being equal to the number of faces.

Name: Polyhedron
Prev: Plane
Next: Flune, or sometimes time (though time is somewhat useless when talking about geometry).
