Answer:

#"Density, "rho~=0.33*g*cm^-3#.

Explanation:

#"Density"# is simply the quotient, #"mass"/"volume"#.

Given 2 of the 3 parameters, thus we can work out the third.

Here, we have been given (conveniently!) #(i)# the mass, and #(ii)# the volume. So we take the quotient:

#((i))/((ii)) ="mass"/"volume"# #=# #(9*g)/(27*cm^3)# #=# #??*g*cm^-3#, and doing the problem with dimensions included gives us an answer in #g*cm^-3# as required.
