                        It does not have any edge or vertex.               When a sphere is cut into halves, each part
                        It has a curved face.                              is a hemisphere.               Edge  Plane face
                                                                            It has two faces (one plane
                        Example: Football.                                 and other curved).

                  difference between a cube and a cuboid

                        In a cuboid, the opposite rectangular faces are of the same shape and size, whereas
                       in a cube, all square faces are of the same shape and size.

                        In a cube, all the edges are equal, whereas in a cuboid, the edges can be of different sizes.

                           Quick Check
                        Identify the solid shapes that you see in each of the following objects:

                         1.                      2.                      3.                      4.
