(a) The unit weight of a sand backfill was determined by field measurements to be
1746 kg per cu.m. The water content at the time of test was 8.6% and the unit
weight of the solid constituents was 2.6 gn per cu. cms. In the laboratory the void
ratio's in the loosest and densest states were found to be 0.642 atd 0.462
respectively. What was the relative density of the fill ?
