Dodecahedron.
"a shape with twelve sides is called a 12-gon..... i promise its in my math book!" Officially its called a dodecagon. Often polygons with a lot of sides start being called x-gon where x is the number of sides.
There are many possibilities, and here are a couple: A dodecagonal prism (dodecagon = 12 sided plane figure); A heptagonal pyramid (heptagon = 7 sided plane figure).
If the shape is flat is is called a: dodecagon If it is a 3 dimensional object it is called a dodecahedron

A dodecahedron is a 3-d shape with 12 faces that are regular pentagons.
A twelve sided shape is called a "dodecahedron" :D
A solid figure with 12 faces is called a dodecahedron.
dodecahedron
A 3-d shape made from pentagonal faces is a dodecahedron (12 sides).
An 8-faced 3D shape is called an octahedron. It is a polyhedron with eight triangular faces, 12 edges, and six vertices.
not posssible, a pentagon specifically means a shape with 5 sides. penta = 5.
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 the edges. See related link for an illustration of a net you could print out.
A twelve-faced shape is a dodecagon, also known as a dodecahedron.
It is a 12 faced shape
It is a dodecahedron - a shape with 12 faces which are regular pentagons.
A 3D pentagon could be called a pentagon prism or a dodecahedron which is a Platonic solid with 12 pentagonal faces.
