Identifying Faces, Edges, and Vertices of Polyhedra

In this video, Mr. Jay explains the concepts of faces, edges, and vertices in 3D shapes. He defines each term and provides examples using a rectangular prism and a square pyramid. For each shape, he identifies and counts the number of faces, edges, and vertices, helping viewers understand these geometric properties.
