During the completion of a construction project, a soil sample was taken from an area of compacted earth fill for a sand-cone in-place density test. The following were obtained from the results of the test: • Weight of sand used to fill the test hole and the funnel of the sand-cone device = 845 g • Weight of sand to fill the funnel of the sand-cone device = 323 g • Unit weight of sand = 15.71 kN/m3 • Weight of wet soil excavated from test hole = 622 g • Moisture content of the soil excavated from the test hole = 16% %3D %3D Calculate the dry unit weight (kN/m³) of the excavated material
