Assume that 50,000 yd3 of the soil from the borrow

Assume that 50,000 yd3 of the soil from the borrow pit is to be delivered to an embankment at a construction site. By the time it reaches the site, the water content is 9%. It will be compacted to a minimum of 90% of modified Proctor maximum dry density. Determine the total volume of water (in ft3) that must be added to the soil to increase the moisture content to the optimum level.
Dry unit weight of soil in borrow pit 87.0 pcf
Moisture content in borrow pi 13.0%
Specific gravity of the soil particles 2.70
Modified Proctor optimum moisture content 14.0%
Modified Proctor maximum dry density 116.0 pcf.?
