a cube, for example
There can be no simply connected polyhedron with those values since they are not consistent with the Euler characteristic.
3 faces and 8 corners
A cube has 6 faces and 8 corners.
A square is not a polyhedron, it is a polygon. A cube is not a polygon, it is a polyhedron.A square has 4 edges and 4 vertexes. It has no faces because it is not a polyhedron. If you cut the corners off of a square, the new polygon has 8 edges and 8 vertexes.A cube has 6 faces, 12 edges, and 8 vertexes. If you cut the corners off of a cube, the new polyhedron has 14 faces, 36 edges, and 24 vertexes.
A cube has 6 faces, 12 edges, and 8 vertices (corners.)
6 faces 8 corners
Cuboid has : 8 corners (vertices) 12 edges 6 faces
A Cuboid has 6 faces, 8 corners, 12 edges.
12 edges 6 faces 8 corners
The answer is a polyhedron
5 faces 9 edges 6 corners
6 faces 8 corners and 12 edges
