6 flat surfaces - known as faces, 12 edges 8 vertices.
A triangular based pyramid (a tetrahedron) has 4 flat triangular faces, 6 edges and 4 vertices
A triangular based pyramid has 4 flat faces, 6 edges and 4 vertices.
A tetrahedron is a triangular based pyramid that has 4 faces, 6 edges and 4 vertices.
A cube or cuboid have 6 flat surfaces and 8 vertices. (A cuboid means shaped like a cube - an example being a shoe box.)
A triangular based pyramid would fit the given description.
Vertices = 4Faces = 4 Edges = 6.
a cube has 8 vertices 12 edges and 6 faces to of which are bases
