Question

How much volume (in cm3) is gained by a person who gains 11.1 lbs of pure fat?

Answer 1

The density of human fat is $0.918 g/cm^{3}$. The mass of the pure fat is 11.1 lbs.

First convert mass from lb to g as follows:

1 lb=453.592 g

Thus,

$11.1 lb\rightarrow 11.1\times 453.592 g=5034.875 g$

Density of a substance is defined as mass per unit volume, thus volume can be calculated as:

$V=\frac{m}{d}$

Putting the values,

$V=\frac{5034.875 g}{0.918 g/cm^{3}}=5484.61 cm^{3}$

Therefore, volume gained by person will be $5484.61 cm^{3}$.
