That depends on the pressure and temperature of the air in the cubic meter.
Any time you change the pressure or the temperature of a gas, you change
the number of molecules in one cubic meter of it.

The answer will depend on the temperature and pressure.
One cubic meter always has 1000 liters, no matter what is inside. On the other hand, 6 bars is approximately 6 times the normal atmospheric pressure, so - according to the ideal gas law - the cubic meter of compressed air would be equivalent to 6 cubic meters of "normal" air.
When it is at a lower pressure or a higher temperature.
You multiply the volume of the gas by its density. The volume will depend on the specific gas, and on the pressure and temperature of the gas. As an example, a cubic meter of air has a mass of approximately 1.2 kg/m3. For other gases, the numbers may be quite different.
Oh, dude, one cubic meter is equivalent to about 1,000 kilograms, which is like one metric ton. So, if you're into precision, it's technically 1 metric ton per cubic meter. But hey, who's counting, right?
