Math, microeconomics or criminal justice
each box weighs 3/5 = 0.6 pound
that's assuming each box weights the same
if they dont' then all you know is each base weighs somewhere between 0 and 3 pounds
such as 4 weigh 1/2 pound each and the 5th weights 1 pound
or
3 weigh 1/3 pound each and the other two weight 1 pound each
or
1 weights 2 pounds and the other 4 weigh 1/4 pound each
