Q:

What is a 3D pentagon shape called?

A:

One term used for a 3D pentagon is a shape called a pentagonal prism. According to Reference.com, this is the polygon that results when you take a pentagon, transcribe a copy of it, and connect the two pentagons using five quadrilateral faces.

The pentagonal prism should not be confused with a pentahedron, which is a 3D polyhedron with five faces. An example of a pentahedron would be a triangular prism – two triangles and three quadrilaterals.

A pentagonal prism is a kind of heptahedron because it has seven faces – two pentagons and five quadrilaterals. Additionally, a pentagonal prism has 15 edges and 10 vertices.
