Problem 3 Following are the results of a sand cone method test Density of Ottawa sand Mass of Ottawa sand to fill cone In the field: = 1548 kg/m³ = 0.149 kg Mass of bottle + sand (before use) Mass of bottle + sand (after use) Mass of moist soil removed from hole Moisture content of removed soil = 3.85 kg = 2.17 kg = 1.858 kg = 13% (a) Calculate the dry density of the field soil (b) If the maximum dry density in the lab was determined to be 1690 kg/m³, calculate the relative compaction
