According to the test results, the thickness of a plastic mulch with a thickness of 0.01 mm cover an area of ​​6.44 kg. Using this as a base, the ratio of various plastic film thicknesses to 0.01 gives the corresponding amount of plastic film. For a plastic film with a thickness of 0.09 mm, the dosage of one flat cover is: 6.440.0090.01 = 5.79. If a farmer has planned 3 mu of vegetables, the coverage rate is 70%. Ask how many kilograms need to buy? Solution: 6.440.930.7 = 12.17 kg. That is, it is necessary to purchase 12.17 kg of plastic film with a thickness of 0.009 mm.
