The endo-dodecahedron is concave and equilateral it can tessellate space with the convex regular dodecahedron. It is possible to go past these limiting cases, creating concave or nonconvex pyritohedra. The regular dodecahedron represents a special intermediate case where all edges and angles are equal. The pyritohedron has a geometric degree of freedom with limiting cases of a cubic convex hull at one limit of collinear edges, and a rhombic dodecahedron as the other limit as 6 edges are degenerated to length zero. Honeycomb of alternating convex and concave pyritohedra with heights between ± 1 / φ The convex regular dodecahedron is one of the five regular Platonic solids and can be represented by its Schläfli symbol While the regular dodecahedron shares many features with other Platonic solids, one unique property of it is that one can start at a corner of the surface and draw an infinite number of straight lines across the figure that return to the original point without crossing over any other corner. The elongated dodecahedron and trapezo-rhombic dodecahedron variations, along with the rhombic dodecahedra, are space-filling. The rhombic dodecahedron can be seen as a limiting case of the pyritohedron, and it has octahedral symmetry. The pyritohedron, a common crystal form in pyrite, has pyritohedral symmetry, while the tetartoid has tetrahedral symmetry. Some dodecahedra have the same combinatorial structure as the regular dodecahedron (in terms of the graph formed by its vertices and edges), but their pentagonal faces are not regular: All of these have icosahedral symmetry, order 120. There are also three regular star dodecahedra, which are constructed as stellations of the convex form. The most familiar dodecahedron is the regular dodecahedron with regular pentagons as faces, which is a Platonic solid. In geometry, a dodecahedron (from Ancient Greek δωδεκάεδρον ( dōdekáedron) from δώδεκα ( dṓdeka) 'twelve', and ἕδρα ( hédra) 'base, seat, face') or duodecahedron is any polyhedron with twelve flat faces. It is not to be confused with Roman dodecahedron. It has a gazillion different shapes! (Fourteen, to be exact.This article is about the three-dimensional shape. a cube, which is a special case of a rectangular prism – you may want to check out our comprehensive volume calculator. If you're searching for a calculator for other 3D shapes – like e.g. Solve it manually, or find it using our calculator. That's again the problem solved by the volume of a rectangular prism formula. Your good old large suitcase, 30 × 19 × 11 inches or You have to pack your stuff for the three weeks, and you're wondering which suitcase □ will fit more in: You are going on the vacation of your dreams □. But how much dirt should you buy? Well, that's the same question as how to find the volume of a rectangular prism: measure your raised bed, use the formula, and run to the gardening center. For that, you need to construct a raised bed and fill it with potting soil. The time has come – you've decided that this year you'd like to grow your own carrots □ and salad □. It is a similar story for other pets kept in tanks and cages, like turtles or rats – if you want a happy pet, then you should guarantee them enough living space. If you're wondering how much water you need to fill it, simply use the volume of a rectangular prism formula. It's in a regular box shape, nothing fancy, like a corner bow-front aquarium. You bought a fish tank for your golden fish □. Where can you use this formula in real life? Let's imagine three possible scenarios:
