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.
Hexagonal prism
It has 6 faces, 12 edges and 8 corners or vertices
There are an infinite number of 3d shapes. For example you can have an infinite number of prisms with ends that are triangular, quadrilateral, or in the shape of any polygon.
A cube is a 3 dimensional figure that has 6 faces, 12 edges and 8 vertices

a cuboid has 6 faces, 12 edges and 8 vertices this is a 3d cuboid incase you get mixed up
Faces= 2 edges=5 vertices=12 Faces= 2 edges=5 vertices=12
Hexagonal prism
a square
The rule applies to POLYHEDRA (3D shapes) not Polygons, which are 2D Faces + Vertices - Edges = 2
There is no 3d shape made up of octagons. An octahedron can be one of several different shapes - but without ANY octagonal faces. For example, A hexagonal pyramid (8 faces, 18 edges, 12 vertices) A heptagonal pyramid (8 faces, 14 edges, 8 vertices) A quadrilateral dipyramid (8 faces, 12 edges, 6 vertices)
It has 6 faces, 12 edges and 8 corners or vertices
It is a cuboid
