How much meters cubed is 20 ton?

Answer 1

This question cannot be answered in a sensible way. A cubic metre is a measure of volume, with dimensions [L3]. A ton is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions without additional information. 20 tons of lead, for example, will occupy far less volume than 20 tons of helium.

Answer 2

To convert tons to cubic meters, you need to know the density of the material. For example, if the material has a density of 1 tonne per cubic meter, then 20 tons would be equal to 20 cubic meters.
