The source for these numbers are chelsea's and beshine's faq
The only 2 problems with the volume calculation is:
1. the weight of Chelsea's implants also include 2500 grams of pp-string with a density of 0,91 g/cc
2. the weight of Beshine's implants also include approx. 1100grams of silicon outer shell with a density of 1,25 g/cc
and assuming that the serum Chelsea's body produced has the same density as Beshine's saline solution, could lead to Chelsea having more cc's.
But I call it a draw.
