A compacted soil fill is to be constructed with a compacted volume of 50,000 m3, a water content of 20%, and a bulk unit weight of 20 kN/m3. Soil can be borrowed from two potential borrow pits: Area A: e = 0.80, w = 16%, Gs = 2.65 Area B: e = 0.60, w = 12%, Gs = 2.65 Find the ratio of the volume of soil to be excavated from Area A to Area B to construct the required fill.
