Answer:

#"Density"="Mass"/"Volume"=0.15*g*cm^-3#.

Explanation:

And thus #rho_"sugar cube"=(0.5*g)/(1.5*cmxx1.5*cmxx1.5*cm)#

#=0.15*g*cm^-3#

While it is bit of a pfaff to include the units in these types of calculation, note that it gave us units that are consistent with units of density, i.e. #"mass"/"volume"=g*cm^-3# or #g*mL^-1#, and thus it is a check on our calculations. It is all too easy to divide instead of multiply or vice versa, and totally botch the answer.
