First convert mass from lb to g as follows:

1 lb=453.592 g

Thus,

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

Putting the values,

Therefore, volume gained by person will be .

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
