Solid shapes have attributes like face, vertices, edges that describe them.

Individual flat surfaces are called faces. Faces meet in straight lines called edges and points called vertices.

**Edges** − The line segments that form the skeleton of the 3D shapes are called edges.

**Faces** − Flat surfaces enclosed by edges are called faces. A face of a solid shape is a plane or 2d figure.

**Vertices** − The corners where the edges meet are called vertices.

A rectangular prism has 6 faces 8 vertices and 12 edges.

A square pyramid has 5 faces 5 vertices and 8 edges.
