(a) Plot the mass diagram for the earthwork quantities contained in the accompanying table. The initial ordinate has been arbitrarily set at \( 5,000 \mathrm{~m}^{3} \). (b) Calculate the total earthwork costs for this project using the following data. Free haul distance \( =300 \mathrm{~m} \) Excavation costs (including \( 300 \mathrm{~m} \) free haul) \( =\$ 5.00 / \mathrm{m}^{3} \) Borrow (including cost of hauling) \( =\$ 10.50 / \mathrm{m}^{3} \) Cost of overhaul \( =\$ 7.00 / \) sta-m Cost of waste is included in cost of excavation.
