cube 8
no. a 2d square has only 1 face but a 3d square (cube) has 6 faces.
The description given fits that of cones
A tetrahedron is the smallest possible polyhedron: a closed 3-d shape with polygonal faces. It has 4 triangular faces, 4 vertices and 6 edges.
Something with 6 faces and 8 vertices

There is no such thing as a polyhedon hexagon.A regular hexagon will tessellate and so it forms a plane (2-D) surface, not a 3-D shape. A 3-D shape with six faces is a hexahedron and this could be a triangular bipyramid with 5 vertices, a parallelepiped with 8 vertices, a pentagonal pyramid with six vertices. There are also other possible shapes.

I believe that such an object cannot exist in normal 3-d space. If there are 6 vertices, the maximum number of edges is 12.
