# 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
