According to Euler none; for all 3d shapes: Vertices + Faces = Edges + 2 ⇒ 12 + 8 = 19 + 2 ⇒ 20 = 21 So unless 20 does equal 21, no 3d shape has 8 faces, 19 edges and 12 vertices. Any 3d shape with 8 faces would be an octahedron.
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?
Hexagonal prism
A 3d shape with 5 faces can be a square pyramid
3d shape Well actually it is a Cube
12, surely.
The 3D shape that has 12 faces is called a dodecahedron. It is a polyhedron with 12 regular pentagonal faces. Each face of a dodecahedron is a regular polygon with five sides of equal length and five equal interior angles.
A cube or cuboid.
It is a dodecahedron - a shape with 12 faces which are regular pentagons.
