faces will the new polyhedron have?

Expert Answer
Each of the 8 vertices of the cube has now been replaced by three vertices of a triangle. So there are now 24 vertices. The cube had 6 square faces. Now those faces are still there but have become octagons. Additionally, there are now 8 new triangular faces. So there is a total of 14 faces.
