How many sides, edges, and vertices does each polyhedron have?
faces: 6, edges: 4 + 4 + 4 = 12, vertices: 4 + 4 = 8
faces: 5, edges: 3 + 3 + 3 = 9, vertices: 6
faces: 4, edges:6, vertices: 4
faces – a flat surface
edges – line segments where faces intersect
vertex – a point where 3 or more edges intersect
