              Now, observe how the 5-faced and 4-faced cubes are formed using the following nets.




                                                   Open cube                                            Hollow cube


                                                                                      4-faced cube
                               5-faced cube

              nets of a cuboid

              We know that in  a cuboid,  the  flat surfaces are

              rectangles  instead  of squares.  A cuboid  and  its  net
              are shown  here.  Observe that  the  opposite faces  of
              a cuboid are equal.

                       Practice time 8e



                1.  Complete the following table.

                             Name of        Number of        Number         Number        Number of      Number of
                               shape          face(s)       of plane       of curved        edge(s)        vertices
                                                             face(s)         face(s)

                      (a) Cube
                      (b) Cuboid

                      (c) Cylinder
                      (d) Cone

                      (e) Sphere
                       (f) Hemisphere

                2.  give two examples of real life objects that have:

                    (a)  only curved face           (b)  only flat face

                    Also, draw them in your notebook.

                3.  Which of these nets can be used to form a cube?

                    (a)                             (b)                              (c)





                4.  Complete the net of cube and cuboid.

                    (a)                             (b)
