What Is a 12-Faced Shape Calle... Home Math Geometry Shapes. What Is a 12-Faced Shape Called? A dodecahedron is the name given to a polyhedron made up of 12 equal pentagons. It is one of the five Platonic solids: a group of regular, convex polyhedrons made up of congruent, polygonal faces.


An eight-faced 3D shape is called an octahedron. Any 3D shape (polyhedron) ends in -hedron, just like any 2D shape (polygon) ends in -gon, and octa- means 8.


A pentagon is a 2-D shape. There is a 3-D shape with 12 faces, each a regular pentagon. It's called a dodecahedron. To make one out of (stiff) paper, you would cut out a "net", then fold and glue ...


What Is a 12-Sided Shape Called? A 12-sided shape is called a dodecagon. A dodecagon is a type of polygon, which is a two-dimensional shape comprised of straight lines. These lines connect to each other to form a closed shape. The name dodecagon is derived from the Greek words meaning "twelve" (dodeca) and "angles" (gon). Polygons are ...


In geometry, a dodecahedron (Greek δωδεκάεδρον, from δώδεκα dōdeka "twelve" + ἕδρα hédra "base", "seat" or "face") is any polyhedron with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron, which is a Platonic solid.There are also three regular star dodecahedra, which are constructed as stellations of the convex form.

A ten sided 2-D shape is a 10-sided polygon. The term decagon can be used for both regular and general 10-sided polygons depending on context, although unqualified it usually refers to the regular 10-sided polygon (i.e. all internal angles are the same and all side lengths are the same.)


Dice are often sold in sets, matching in color, of six different shapes. Five of the dice are shaped like the Platonic solids, whose faces are regular polygons. Aside from the cube, the other four Platonic solids have 4, 8, 12, and 20 faces, allowing for those number ranges to be generated.


actually i am not sure what you mean by three dimensional object as i have described a 2 dimensional manifold. a three dimensional object should have some 3 dimensional faces. i guess i thought you meant a closed surface that does not embed in 2 space, which is the lay persons notion of a three ...
