A compacted fill with a total volume of 40,000 cubic yards is to be constructed as a surcharge for a highway construction project. Specifications require that the soil be compacted to a minimum dry unit weight of 116.9 pcf with a minimum water content of 5.5 percent. Soil in the borrow area has an average unit weight (total) of 108.5 pcf and a water content of 4.0 percent. Estimate how many cubic yards of borrow material must be excavated and what the minimum amount of water to be added is.
