In the table given below, write down the number of faces, edges and vertices. Shapes Faces Plane Curve Edges Plane Curve Vertices

The face of a solid is the flat surface which forms part of the boundary of the solid object. Number of plane faces of a cube = 6 Number of curved faces of a cube = 0 The edges are the lines formed from the intersection of two faces of the solid. Number of plane edges of a cube = 12 Number of curved edges of a cube = 0 A vertex is a point where three or more edges meet. Number of vertices of a cube = 8 The face of a solid is the flat surface which forms part of the boundary of the solid object. Number of plane faces of a cuboid = 6 Number of curved faces of a cuboid = 0 The edges are the lines formed from the intersection of two faces of the solid. Number of plane edges of a cuboid = 12 Number of curved edges of a cuboid = 0 A vertex is a point where three or more edges meet. Number of vertices of a cuboid = 8 The face of a solid is the flat surface which forms part of the boundary of the solid object. Number of plane faces of a cylinder = 2 Number of curved faces of a cylinder = 1 The edges are the lines formed from the intersection of two faces of the solid. Number of plane edges of a cylinder = 0 Number of curved edges of a cylinder = 0 A vertex is a point where three or more edges meet. Number of vertices of a cylinder = 0 The face of a solid is the flat surface which forms part of the boundary of the solid object. Number of faces of a sphere = 0 Number of curved faces of a sphere = 1 The edges are the lines formed from the intersection of two faces of the solid. Number of plane edges of a sphere = 0 Number of curved edges of a sphere = 0 A vertex is a point where three or more edges meet. Number of vertices of a sphere = 0 The face of a solid is the flat surface which forms part of the boundary of the solid object. Number of plane faces of a cone = 0 Number of curved faces of a cone = 1 The edges are the lines formed from the intersection of two faces of the solid. Number of plane edges of a cone = 0 Number of curved edges of a cone = 0 A vertex is a point where three or more edges meet. Number of vertices of a cone = 0 The table is as follows: Shapes Faces Plane 6 6 0 0 0 Curve 0 0 2 1 1 Edges Plane 12 12 0 0 0 Curve 0 0 0 0 0 Vertices 8 8 0 0 0
