Okay my little math whiz friends I need help calculating something and I so truly suck at math it's pretty much sad....

I have a space we'll call it...it is 6 feet wide by 3 feet deep and is 9.5 feet tall. Now I know that gives me 18 sq feet but how does one figure out the true volume I guess you'd call it of this space. Basically a 6 foot x 3 foot retangle that is also 9.5 feet in height?

Help me please oh math smart members.
