An acrylic container having a volume of 0.30 ft is filled with dry sand under relatively loose condition. The dry weight of the sand in the container is 31 lb. Water is then carefully added to the container so as not to disturb the condition of the sand. When the container is filled with water, the sand becomes fully saturated, and the combined weight of solids plus water is 38.2 lb. From these data, determine all of the following: (A) Void ratio of the sand in the container. (Show all pertinent volume-weight relationships and calculations.) (B) Specific gravity of the soil solids. (Show all pertinent volume-weight relationships and calculations.) (C) Saturated unit weight, and dry unit weight, of the sand, in lb/ft and kN/m³. (Show all pertinent volume-weight relationships and calculations.)
