A square base pyramid
Hexagonal prism
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.

Cube or cuboid (3D figure) - 12 edges Dodecagon Deodeca (2D figure) Octahedron - (3D figure) - 8 faces 12 edges 6 vertices cube, rectangular, prism, pyramid
An isosahedrons has 12 edges many. A cube is one example.
A cube. Except that the word is vertices, not vertixes.
A cube or a cuboid could have 12 edges, 8 vertices, and 6 faces.
