Faces, Vertices and Edges of a 3-dimensional Figure: (i) Faces: Each flat part of a solid is called its face. (ii) Vertices: Each corner where three faces of a solid meet is called its vertex. The plural of vertex is vertices. (iii) Edges: The two faces of a solid meet in a line, called an edge. Now, we shall discuss about the faces, vertices and edges of some 3-dimensional figures having flat faces. A solid bounded by six rectangular plane faces is called a cuboid. A box, a matchbox, a book, a brick, a tile, etc., are all in the shape of a cuboid. In the adjoining figure, ABCDEFGH is a cuboid.
