A dodecahedron is a 3-d shape with 12 faces that are regular pentagons.
A 3D pentagon could be called a pentagon prism or a dodecahedron which is a Platonic solid with 12 pentagonal faces.
A regular 3-d figure formed from pentagons is a dodecahedron (12 faces). However, a soccer ball is not a 3-d shape formed from only regular pentagon. Instead it comprises 12 regular pentagons (usually black) and 20 regular hexagons (white).
A pentagon is a 2 dimensional object. The 3 dimensional object, with 12 pentagonal faces, is called a dodecahedron.
12, if you mean a dodecahedron, a 3-d figure with only pentagonal faces.
A 3-d shape made from pentagonal faces is a dodecahedron (12 sides).
A dodecahedron (literally, "12 face solid").The "regular dodecahedron" has 12 identical faces, all regular pentagons ("5 sided flat shape").But there are many, many other 3d shapes with 12 faces, including the rhombic dodecahedron which has 12 identical faces, all 4 sided parallelograms.what shape has 12 faces?
A dodecahedron - fromed from 12 regular pentagons.
An edge of a 3-d pentagon is the intersection of two of its adjacent faces.
the other faces on a pentagonal prism would be rectangular
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.
A flat pentagon. Or some kind of circle pentagon breed...
