11. The proposed embankment fill requires 8000m of compacted soil. The void ratio of the compacted fill is specified as 0.70. Four borrow pits are available as described in the following table, which list the respective void ratios of the soil and the cost per cubic meter for moving the soil to the proposed construction site. Assume that the specific gravity is the same at all pits, which among the pits should be bought to minimize the cost? Cost (P/m³) 400 Borrow Pit Void Ratio A 0.82 B 0.9 450 1.1 250 D 0.78 600
