The person who have gained 11 lb. of pure fat will gain 5,500 cm³ of volume.
It is given in the question that the person gains 11 lb. of pure fat.
We have to find the volume (in cm3 ) gained by the person.
We know that,
The density of fat is about 0.9 grams/ml
Converting this in pounds, we get :-
0.9 grams/ml * 1 lb. / 454 grams * 1 ml / 1 cm³= 0.002 lb./cm³
We know the formula of density:-
Density = mass / volume
Hence,
Volume = mass / density
Volume = 11 / 0.002
Volume = 5,500 cm³.
