The regular dodecahedron is one of the five Platonic solids, the others beng the tetrahedron, cube, octahedron, and icosahedron. The regular dodecahedron has a total of twelve faces, twenty vertices, and thirty edges. Each face is a regular pentagon, which means that it has five sides of equal length and five angles of A dodecahedron is a 3D polygon (or polyhedron) with 12 sides. It's in the name: dodeca = 12, hedron = 3D polygon. It has sides/edges and vertices. It's volume is given by the formula: where is the length of an edge History. Dodecahedron. One of the five types of regular polyhedra. A dodecahedron has 12 (pentagonal) faces, 30 edges and 20 vertices (with three edges meeting at each Answer: A dodecahedron has 12 sides. Step-by-step explanation: Hope that helps! A dodecahedron must have 12 faces, but it can have any number from 8 to 20 vertices and so 18 to 30 edges. How many faces does a dodehedron? If you mean a dodecahedron then it has 12 faces, 30 edges and 20 vertices How many sides does a dodecahedron have? Get the answers you need, now! keeru keeru Math Secondary School answered How many sides does a dodecahedron have? From left to right the solids are tetrahedron (four sides), cube (six sides), octahedron (eight faces), Why is it called a dodecahedron? Dodecahedron is derived from the Greek word “dōdeka” means “12” and “hédra” means “face or seat” that shows that it is a polyhedron with 12 sides or 12 faces. Hence, any polyhedra with 12 sides can be called a dodecahedron. It is made up of 12 pentagonal faces A dodecahedron is a regular three-dimensional figure, so all of its faces have the same shape and all of its sides have the same length. Therefore, we can calculate its volume

What is a 12 faced shape called? dodecahedron In geometry, a dodecahedron (Greek δωδεκάεδρον, from δώδεκα dōdeka “twelve” Since the first dodecahedron was found in , more than of these objects — hollow sided shapes ranging from about 5cm to 10cm in diameter, with holes of. These A dodecahedron's faces are pentagons (5 sides). There are 12 faces, and 3 faces meeting at each vertex (corner). Model of a dodecahedron. It is not actually a regular dodecahedron, although it has 12 faces, each with 5 sides, but it is quite close. Roman dodecahedron
