How many trips would one rubber-tired Herrywampus haveto make to backfill a space with a geometrical volume of5,400 cubic yard? The maximum capacity of the machine is30 cubic yard (heaped), or 40 tons. The material is to becompacted with a shrinkage of 25% (relative to bank measure)and has a swell factor of 20% (relative to bank measure).The material weighs 3,000 lb/cu yd (bank). Assumethat the machine carries its maximum load on each trip.Check by both weight and volume limitations.

Question
How many trips would one rubber-tired Herrywampus have
to make to backfill a space with a geometrical volume of
5,400 cubic yard? The maximum capacity of the machine is
30 cubic yard (heaped), or 40 tons. The material is to be
compacted with a shrinkage of 25% (relative to bank measure)
and has a swell factor of 20% (relative to bank measure).
The material weighs 3,000 lb/cu yd (bank). Assume
that the machine carries its maximum load on each trip.
Check by both weight and volume limitations.
