Three times as many cement bags is 3*80 = <<3*80=240>>240 cement bags.

If a bag of cement weighs 50 kg, 3/5 times as much weight is 3/5*50 = <<3/5*50=30>>30 kgs.

If the cost of transporting 80 bags of cement, each weighing 50 kgs, is $6000, the cost of transporting one bag of cement weighing 50 kg is $6000/80 = $<<6000/80=75>>75

Since a bag weighing 50 kgs costs $75 to transport, a bag weighing 30 kgs will cost 30* $75/50 = $<<30*75/50=45>>45 to transport.

The cost of transporting 240 cement bags each weighing 30 kgs is $45*240 = $<<45*240=10800>>10800
