A proposed embankment fill requires 5500 m3 of compaction soil. The void ratio of the compacted fill is specified as 0.70. The following four borrow pits are available with their respective void ratio of the soil and cost per cu.m. for moving the soil to the construction site. Borrow Pit Void Ratio Cost per m3 (Pesos) A 0.85 850 B 1.20 640 C 0.95 760 D 0.75 940 Compare the total cost for acquiring soil at each borrow pit and select the pit from which soil should be brought to minimize the cost. Assume Gs to be the same at all pits.
