                            43 cm long blue ribbon. Find the total length                                   +  4 3 cm

                            whose lengths are 58 m and 14 m.
                              Answer: _____________________

                       (c)  A man sold 225 m cloth on Monday and

                              Answer: _____________________

                  MeasureMent of weight (Mass)

                  Divya invites her friend Mansi to her house. Divya’s

                  mother is preparing cup cakes. Divya observes how
                  her mother measures the ingredients.

                  4 cups flour                      6 teaspoons butter

                  4 tablespoons milk                6 cups powdered sugar
                  1 glass butter milk               4 eggs

                  2 bowls dry fruits                3 tablespoons fruit extract

                  Divya’s mother whisks all the ingredients well and bake
                  them. When the cup cake is ready, she puts 2 pinch of
                  sprinkles on each cup cake.

                  Divya noticed that her mother measured the mass of ingredients using cups,

                  tablespoon, teaspoon, pinch, bowl, glass, etc.
                  Cups, glasses, bowls and spoons can be of different shapes and sizes. Pinch measured

                  by thumb and finger can also be different. So, measuring mass in terms of these
                  units are not fixed.
