               8.1  Surfaces with different shapes



                These boxes or blocks have flat surfaces.
                The surfaces are called faces.

















                                                                  Block B



                             Block A


                Each face of Block A is
                a rectangle.

                The four corners look
                exactly the same.

                Each face of Block B is
                a square.
                The four corners look exactly the same.
                The four sides of a square have the same length.


               1. Use your pencil only and try to draw a square. Do not use a
                   ruler or some other straight object.

                   Your drawing must be bigger than the square shown here.
                   Use about half of a page.
