              Now, let us explore the features of some solids.

                             Cube                             Cuboid                    Sphere

                                                                                                     face
                                        Edge                               Edge
                                        Face                               Face



                      6 faces, 12  edges, 8 ver ces   6 faces, 12 edges, 8 ver ces    1  face (curved)
                      All the faces of a cube are    All the faces of a cuboid are    A sphere has no vertex and
                      squares.                       rectangles. Only opposite        no edge.
                                                     faces are equal.

              nets of soLiD

              The flattened  shape  that  can  be  used  to make a  solid  object by  folding  along  the

              marked lines is called the net of a solid shape.
              nets of a cube


              Let  us take a  cubical  hollow box and
              open it by cutting along its edges
              This net of a cube shows the flat surface

              or the faces of the cube.

              Each face is a square of same size.
              Net of a cube can  be drawn  in  many
              ways.  Each of the  following  are nets  of

              a cube.

                    (a)                     (b)                      (c)                     (d)







              Trace these nets on a sheet of paper, cut and fold to make a cube.
