2. A 3.12 lb saturated soil sample collected from a potential borrow pit in a Shelby tube of 3 in diameter and 6 in length. The sample was put into

an oven for 24 hours at 110°C and the dry weight after oven drying was found to be 2.44 lb. Please determine the following parameters: a)Saturated unit weight of the specimen (ysat) b)Dry unit weight of the specimen (yd) c)Moisture content (w %) d)Specific gravity (Gs) e)Calculate the volume of soil required to construct an embankment(shown below in figure) at a dry unit weight of 115 pcf and a water content of 28%.
