A 3 dimensional pentagon has 15 edges
3 dimensional is a cube. it has 8 edges
The regular dodecahedron is the 3-dimensional analog of a regular pentagon. In other words, it is a three-dimensional pentagon.
Assuming you mean a pentagon - not penagon, a 3-dimensional pentagon is a dodecahedron which has 12 faces.
A three-dimensional pentagon does not exist as a distinct geometric shape. The term "pentagon" specifically refers to a two-dimensional polygon with five sides. In three dimensions, the closest equivalent would be a pentagonal prism, which has 10 edges, 7 faces (2 pentagonal bases and 5 rectangular lateral faces), and 5 vertices.
There is no 3 dimensional figure with JUST 3 edges.
