3-4 A borrow pit soil sample has a wet weight of 42 lbs (WT). The soil sample volume is 0.34 cubic feet. A small portion of the sample is used to determine the water content. When wet, the small sample mass is 150 grams, after drying - it is 125 grams. a) What is the water content of the sample? b) Calculate the wet and dry unit weights of the soil in the borrow pit. To calculate the dry sample weight, use formula in the book [3-9a]
