^ 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?
