A proposed grading plan requires 223,120 m³ of cut and 206,670 m³ of fill. Laboratorytests on a series of undisturbed samples from the cut area produced the following results:Sample No.Dry Unit Weight(kN/m³)Moisture Content(%)3-13-25-15-28-117.317.716.817.116.09.19.58.97.212.0A series of modified Proctor tests on representative bulk samples produced a maximumdry unit weight of 19.2 kN/m³ and an optimum moisture content of 10.2%. The projectspecifications require a relative compaction based on the modified Proctor test of at least90%.(a) Determine the shrinkage factor and compute the required volume of import orexport, if any. Use the dry unit weight of the cut when computing any import orexport quantities.(b) Determine the weight of any import or export soil, assuming it has a moisturecontent equal to the average moisture content in the cut. Express your answer inmetric tons (1 metric ton = 1000 kg = 1 Mg).
