One example is an icosahedron.
Actually, it has to be an icosahedron - the name means a polyhedron with 20 faces!
the name of a 20 sided 3d shape is called a icosahedron
Icosahedron
well. it is called icosahedron
An edge.
They both have a face, not a :) face but a side of a shape is called a face and a 2d and 3d shape both show a face of the shape

A cylinder is a 3d shape because you can see the in side of it.
An icosahedron is a polyhedron has 20 faces, and is a 3D shape.
The faces in a 3-D shape (polyhedron, for example) are bordered by edges.
A 12 sided 3D shape is called a dodecahedron.
A 3D 5 sided shape is called a dodecahedron. It is a solid with 20 vertices, 30 edges and 12 equal pentagonal triangular faces.
To answer this question more details need to be provided. For example one a 3D shape one side is called a face.
