URGENT - Convert m3 salt to tonnes

URGENT - Convert m3 salt to tonnes   (05/13/2014, 3:08 AM)

Hello,

There are two vehicles, one with a capacity of 9m3 and the other 6m3.

How do I work out their capacity for salt? I found the following online but can't work out the calculation:

Salt = 801 kg/m3

If you can show me the whole calculation I would be very greatful.

Many thanks :)
