Take a guess as to what the density of a human would be. support your prediction with real life experiences

~1 g/mL

Explanation:

With a normal amount of air in our lungs, we can float in a pool with with our nose and mouth above water.

However, if we exhale, we sink.

Since we float or sink depending on the amount of air in our lungs, the density of the human body must be close to that of water.
