loga (2) = 0.3812
loga (3) = 0.6013
loga (5) = 0.9004
and we should know that loga a = 1

∴ loga (30a)³ = 3 loga (30a)   = 3 loga (2 * 3 * 5 * a)    = 3 ( loga 2 + loga 3 + loga 5 + loga a )   = 3 ( 0.3812 + 0.6013 + 0.9004 + 1 )
                   = 3 * 2.8829    = 8.6487
The correct answer is option C. 8.6487
