6. The earthwork for a road is shown in the below Mass Diagram, in which the dashed lines represent balance lines based on an LEH of 1000 ft. a) Find the amount of unused cut needed to be disposed of (Waste). b) Find the amount of the earth needed to be bought (Borrow) for the unprovided fill. c) If, after taking into account the free haul distance, the average unit cost is $0.02/ft-ft, what will be the approximate cost of overhauling the usable cut earth for filling within the balanced zones?
