Railway wagon

The railway wagon holds 75 m3 load. Wagon can carry a maximum weight of 30 tonnes. What is the maximum density that may have material with which we could fill this whole wagon?

b) what amount of peat (density 350 kg/m3) can carry 15 wagons?

Correct result:

h =  400 kg/m3
b =  393750 kg


V=75 m=30 1000=30000 h=m/V=30000/75=400 kg/m3
h2=350 h2<h a=V h2=75 350=26250 b=15 a=15 26250=393750 kg
