  • They divided each foot into twelve equal parts called inches.<\/li>\n
  • Then they divided each inch into smaller parts.<\/li>\n<\/ul>\n

    Question 2.
    \nWhy there is a need to develop an internationally accepted instrument for measuring lengths?
    \nAnswer:<\/p>\n

      \n
    • Each country had its own scale which differs from others, so it lead to commerce a lot of problems in trade and commerce.<\/li>\n
    • So each country in the world began to make their own sales.<\/li>\n
    • Finally in France, it was decided that a certain length of rod made of a special material (Platinum – Iridium) would be called a meter.<\/li>\n
    • This was finally accepted as an instrument of measuring lengths.<\/li>\n<\/ul>\n

      Question 3.
      \nWhat is the standard unit of length? How is it divided into smaller units?
      \nAnswer:<\/p>\n

        \n
      • Meter is the standard unit of length.<\/li>\n
      • The centimeter and millimeters are smaller units of length
        \n\"AP<\/li>\n
      • 1 Meter (1 m) = 100 centimeters (100 cm)<\/li>\n
      • 1 Centimeter (1 cm) = 10 millimeters (10 mm)<\/li>\n<\/ul>\n

                  • Our eyes must be vertically above the point of coincidence of scale where the measurement is to be taken.<\/li>\n
                  • Ensure that the ends of scale are not worn out.<\/li>\n
                  • Measure the length of an object more than two times and then take the average of these measurements for accuracy.<\/li>\n<\/ul>\n

                    Question 2.
                    \nHow do you measure the height of your classmate using a meter scale?

                      \nAnswer:<\/p>\n

                        \n
                      • In our day-to-day work, we use a wooden\/plastic scale to measure lengths.<\/li>\n
                      • It is marked or graduated in centimeters and millimeters.<\/li>\n
                      • Take a scale. The zero mark on the scale is made to coincide with one end of the table.<\/li>\n
                      • And the reading at the point which is coinciding with the other end of the table is taken.<\/li>\n
                      • Since a meter-scale has some thickness, we may make an error if the eye is not correctly positioned.<\/li>\n
                      • The correct position of the eye is which is vertically above the end where the reading is to be taken.<\/li>\n<\/ul>\n

                        \nAnswer:<\/p>\n

                          \n
                        • Cut a cardboard into a shape of rectangle having length 4 cm and breadth 2 cm as shown in Figure.
                          \n\"AP<\/li>\n
                        • Let us measure its area. The convenient unit to measure the area of given cardboard would be cm2.<\/li>\n
                        • Take a centimeter graph paper. Each small square on this graph paper has a side equal to 1 cm.<\/li>\n
                        • The area of each small square on this graph paper is 1 cm2.<\/li>\n
                        • Place the cardboard on the centimeter graph paper (figure).<\/li>\n
                        • and draw its outline with the help of a sharp pencil.<\/li>\n
                        • Now remove the cardboard and mark the shape as PQRS.<\/li>\n
                        • Count the number of squares inside the outline. The number of squares is 8.<\/li>\n
                        • Area of the cardboard is equal to the area covered by PQRS on the graph paper.<\/li>\n
                        • Area of PQRS = Total area of unit squares inside the PQRS
                          \n= 8 x area of 1 unit square
                          \n= 8 x 1cm2<\/sup> = 8 cm2<\/sup>
                          \nIn this case, the cardboard we used has a regular shape – rectangle.<\/li>\n<\/ul>\n

                            Question 8.
                            \nNarrate the story of scale?
                            \nAnswer:
                            \nMany hundred years ago, people used to measure distances with their hand-spans, strides or foot-spans.<\/p>\n

                              \n
                            • One day a very tall man went to a shop to buy some cloth. He asked for three and a half arm’s length of cloth.<\/li>\n
                            • The shopkeeper measured three arm lengths of cloth and then added approximately another half-arm length.<\/li>\n
                            • The man felt that the shopkeeper had cheated on him. So he measured the cloth with his arms and found that the cloth was not even three arm lengths.<\/li>\n
                            • He told the shopkeeper that the length of the cloth was less than three-and-a-half arms when he measured with his own arm.<\/li>\n
                            • The shopkeeper replied that his own arm was the standard for measuring. They both argued about whose arm was to be taken as a standard measure.<\/li>\n
                            • In those days, people arguing over measuring the length of fields, ropes, and hundreds of other things must have been a familiar fight. How should one measure a half or a quarter arm length<\/li>\n
                            • Finally, some sensible people got together and decided to have a scale of a fixed length.<\/li>\n
                            • In order to measure subunits, they marked this scale with several smaller but equal divisions.<\/li>\n
                            • They then decided that everyone would measure lengths with this scale.<\/li>\n
                            • They used wood and metal to make scales of the same length.<\/li>\n<\/ul>\n

                              Question 9.
                              \nHow do you measure the volume of a cardboard box?
                              \nAnswer:<\/p>\n

                              • We measure the volume of cardboard with the help of cube boxes.<\/li>\n
                              • Each cube has a measurement of 1 cm length, 1 cm breadth, and 1 cm height.<\/li>\n
                              • The volume of one cube is equal to 1cm x 1cm x 1cm = 1 cm3<\/sup> which is known as 1 cubic centimeter and written as 1 cm3<\/sup>.<\/li>\n
                              • A cubic centimeter is a standard unit for the measurement of the volume of solids.<\/li>\n
                              • Therefore the volume of the rectangular cardboard box is equal to the total number of cubes occupying it. Therefore the volume of a rectangular cardboard box
                                \n= 12 x 1 cm3<\/sup> = 12 cm3<\/sup>.<\/li>\n
                              • However, if we multiply length, breadth and height, it would be
                                \n3 cm x 2 cm x 2 cm = 12 cm3<\/sup><\/li>\n
                              • Therefore, we can say the volume of a box = length x breadth x height<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
