It is an octahedron that is a 3D shape with 8 faces
It is an octahedron. Octahedra may have 6 to 12 vertices and there are 257 topologically distinct convex octahedra.
A 3-D shape that has 8 faces is a hexagonal prism. This is a shape that is formed on a hexagon-shaped base.
A OctahedronThis shape has 8 faces.

A 3-D shape that has 8 faces is a hexagonal prism. This is a shape that is formed on a hexagon-shaped base.
A OctahedronThis shape has 8 faces.
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.
