[Problem MQ-K] The natural soil obtained from a borrow pit exhibits a bulk unit weight of 18.1 kN/m3 and a moisture content of 11.2%. This mechanically extracted soil will be used for creating a trapezoidal subbase with dimensions: 115 m upper base, 175 m lower base, 750 mm thickness, and 2125 m length. The soil is loaded into trucks, each with a capacity of 5.50 m³, resulting in a total load weight of 68.5 kN when fully loaded. Water is then added on-site, increasing the moisture content to 17.3%.

[Problem MQ-K] The natural soil obtained from a borrow pit exhibits a bulk unit weight of 18.1 kN/m3 and a moisture content of
11.2%. This mechanically extracted soil will be used for creating a trapezoidal subbase with dimensions: 115 m upper base, 175 m
lower base, 750 mm thickness, and 2125 m length. The soil is loaded into trucks, each with a capacity of 5.50 m³, resulting in a total
load weight of 68.5 kN when fully loaded.
Water is then added on-site, increasing the moisture content to 17.3%. Subsequently, the soil is compacted to achieve a dry unit
weight of 16.9 kN/m³3. What would be the volume of the pit in the borrow area?
