The average density of the human body is 985 kg/m 3, and the typical density of seawater is about 1020 kg/m 3.a) Draw a free-body diagram of a human body floating in seawater and determine what percentage of the body's volume is submerged.b) The average density of the human body, after maximum inhalation of air, changes to 945 kg/m 3.) Draw a free-body diagram of a human body floating in seawater and determine what percentage of the body's volume is submerged. b) The average density of the human body, after maximum inhalation of air, changes to 945 kg/m 3.
No. The human body's density is very slightly below that of water, as the body contains air pockets that more than make up for the slightly heavier parts, and the rest is just â¦ water itself.6 people found this useful.ell, it's just about the same as that of water, because when you. put the average human being in water, he just barely floats in it. Some people (me, for example) can sink or float depending on how much. air they hold in their lungs, so their density can vary from just.
