There are many options. Some of these are:
A pyramid with a base that is a 19 sided polygon;
A dipyramid with a "centre" that is an 18 sided polygon;
A prism with decagonal bases.
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.
polyhedron
A sphere...
sides are the face of a 3d shape and verticies are the corner of the shape
Yes, the Platonic solids (excluding the sphere which does not have vertices).

A sphere.
A sphere is not a 3dshape
polyhedron
cube
A sphere...
A sphere for example.
How about a sphere or a cylinder
A 3D 5 sided shape is called a dodecahedron. It is a solid with 20 vertices, 30 edges and 12 equal pentagonal triangular faces.
retangle
There is no limit to the number of vertices nor edges.
That 3D shape is called triangular pyramid.
