^ works in math mode (between $ signs), so $x=20cm^3$ will work, but 
"cm" will be in italic type, while units should be roman (am I right?). 
I don't know if this is the right way to do it, but e.g. $x=20$cm$^3$ 
would work, however probably $x=20{\rm cm}^3$ or $x=20\hbox{cm}^3$ would 
be better. Should there be any space between the number and a unit?
