Are the units of volume compatible with the density units?

[nick gear]

do I need to make some unit conversions because this number seems way off to me?

 

[SteamKing]

m= p * v => m = 9.3 g/cm^3 * 4.201 x 10 ^ -4 = .0039

Just as with mistakenly copying numbers between calculations, ignoring units can get you into trouble just as quickly.

What are the units of volume here? V = 4.201×10^-4 what exactly? Are these units compatible with the units in the density of the block?
