it can have 12 edges any 3d square can
cylinder
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.
Spheres
Cubes, cuboids, Trapezoid prisms, octahedrons
3D shapes have edges, sides, and intersecting points
cubes and rectangular prisms
Cylinder
There are infinitely many shapes that do.

Spheres
sphere
A cube has 6 faces
There are lots of shapes: a sphere, an ellipsoid, a smoothed blob.
