There is no such thing in SI as liquid and dry measures for volumes. A cubic meter is the same whether you're measuring water, sand, natural gas or pig manure. In other words, if you have a container having a volume of 1 cubic meter, it doesn't matter what you put in it. If you fill it, you have one cubic meter of whatever it is (as long as it will conform to the shape of the container and leave no gaps).
 
A room is, of course, a container. Unless there's something seriously wrong with your environment, a 27 cubic meter room (for example) will, if unfurnished and unoccupied, contain 27 cubic meters of air.

Thanks a lot everybody for all your help.  I have another question.  I think i read on one of the postings that there are 1000 l in a cubic m of water. In a cubic m of sand or gravel is it still 1000 l? I don't want to sound stupid but i honestly don't know. Thanks again for all your help.
