Answer:

Approx. #7*cm^3#

Explanation:

#rho,"density "Pt=21.45*g*cm^-3#.

Now (after finding out that #1*oz=28.35*g#), our calculation is:

#(28.35*cancelg*cancel(oz^-1)xx5.4*cancel(oz))/(21.45*cancelg*cm^-3)# #~=# #7*cm^3#

I think platinum is currently trading at #$1000" USD"*oz^-1#, so don't lose that ring!
