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.
An ellipsoid with a slice removed.
# of faces + # of edges + # of vertecies + 2
A cube and a regular octahedron have the same number of edges, vertices, and faces. Both have 12 edges, 8 vertices, and 6 faces.
A hexagon has 6 sides, which means it has 6 vertices as well. All 2-D objects have only one face.
They are called a Vertices and it is where 2 edges meet.
Rectangles are 2-dimensional figures- they lie in a plane- they have four vertices There really is no such thing as a 3D rectangle. If you mean a rectangular prism, it has 8 vertices, 4 on each of its two parallel faces.
1. A cube & 2. A rectangular prism

Faces= 2 edges=5 vertices=12 Faces= 2 edges=5 vertices=12
In 2 dimensional space, a vertex is formed when two lines meet at an angle. In 3D space, a vertex is a point where three or more faces meet.A sphere is not an arced line but is one curved surface. It has no vertex.
It Is A Cone
An ellipsoid with a slice removed.
sphere
i would say a cube
