Description: The rhombic dodecahedron derives its name from its twelve ("dodeca-") faces, all of which are congruent rhombi, each formed by joining two tetrahedra. In this article, Cagle and Frost explore these related polyhedra, showing how to exploit their space filling properties to create nets for three intriguing puzzles.
