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.

The 3D shape with 2 octagons and 8 squares is called a truncated square antiprism. It is a type of prism where the top and bottom faces are octagons, and the side faces are squares. This shape has a total of 10 faces, including 2 octagons and 8 squares.
