13. An earth dam requires one million cubic meter of soil compacted to a void ratio of 0.8. In the vicinity of the proposed dam, three borrow pits were identified as having suitable materials. The cost of purchasing the soil and the cost of excavation are the same for each borrow pit. The only difference of the cost for each borrow pit is the cost of transportation. Borrow pit No. Void Ratio 1 2 3 1.8 0.9 1.5 Transportation Cost ($/m³) 0.6 1 0.75 a. Which borrow pit would be the most economical?
