A 3-d shape, all of whose faces are rhombi, is called a parallelepiped.
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.
8 edges and 5 faces
Faces: 5Vertices's: 5Edges:8
