It depends on what you mean by a 3-d pentagon.
To most people, a 3-d pentagon is a dodecahedron - a 3d shape with 12 pentagonal faces. In that case, each of the faces, by definition, must be a pentagon!
If you mean a pentahedron - a 3d shape with 5 plane faces, it could be a triangular prism or a quadrilateral based pyramid. In the first cae the bases are triangles, in the second, a quadrilateral.
What else can I help you with?
How many faces does a 3d pentagon have?
A 3D pentagon itself does not exist as a standalone shape, as a pentagon is a 2D figure with five sides. However, if you're referring to a 3D shape that is based on a pentagon, such as a pentagonal prism or a pentagonal bipyramid, the number of faces would vary. A pentagonal prism has 7 faces (2 pentagonal bases and 5 rectangular lateral faces), while a pentagonal bipyramid has 7 triangular faces.
