In a standard proctor test, 1.8 kg of moist soil was filling the mould (volume = 944 cc) after compaction. A soil sample weighing 23 g was taken from the mould and oven dried for 24 hours at a temperature of 1100C. Weight of the dry sample was found to be 20 g. Specific gravity of soil solids is C = 2.7. The theoretical maximum value of the dry unit weight of the soil at that water content is equal to

1.  4.67 kN/m3

2.  11.5 kN/m3

3.  16.26 kN/m3

4.  18.85 kN/m3
