A borrow pit’s soil is used as earth fill at a construction site. The in situ dry unit weight of the borrow pit soil was determined to be 17.18 kN/ m3. The soil at the site is to be compacted to a dry unit weight of 18.90 kN/m ³ , while the construction project requires 15,000 m3 of compacted soil fill. Determine the volume of soil that must be excavated from the borrow pit to provide the necessary volume of the compacted fill.
