Answer:

Approx. #25*cm^3#..........

Explanation:

#rho#, #"density"# #=# #"mass"/"volume"# by definition. The quoted density, #rho=11.3*g*cm^-3# thus has appropriate units.

To get volume, we thus take the QUOTIENT: #"volume"="mass"/rho#, i.e.

#(282.5*g)/(11.3*g*cm^-3)=??*cm^3#. Is this quotient dimensionally consistent? Why?
