An octahedron
it is some sort of shape
Octahedron
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 answer is a polyhedron
A cube.

A cube
Octagon. * * * * * An octagon is 2-dimensional. The regular 3-d shape (all faces the same) is the octahedron, but a hexagonal prism also has 8 faces.

A 3-D shape with 8 faces is an octahedron.

Octahedron
Its a Octagon * * * * * No. An octagon is a shape with 8 sides. 8 faces implies a 3-dimensional object, which would have to be an octahedron.
A 3-D shape that has 8 faces is a hexagonal prism. This is a shape that is formed on a hexagon-shaped base.
