A proposed embankment fill requires 5000 m² of compacted soil. The specification requires dry unit weight of 18 kN/m, the specific gravity of soil is 2.70. Four borrow pits are available, as described in the following table, which lists the properties of the soil and the cost per m for moving the soil to the proposed construction site. Assume the specific gravity of the soil is 2.70 in each borrow pit. Unit Weight (kN/m³) Moisture Content (%) Cost (Pesos/m) Borrow Pit A 15.8922 11 855 B 13.2435 15 645 17.658 20 765 D 20.3067 15 945 13. Which of the following borrow pit will give the lowest cost for the embankment (indicate the amount)? Example Format: A-5 000 000
