Question

How do you calculate the density of the human body?

Answer 1

Hint :In order to solve this question, we are going to measure the human body’ mass and the volume by taking an equivalent amount of water. Then the two values are converted to the favorable units and are then divided to give the correct value for the density of the human body.
To measure the density, the formula is.
 $ density = \dfrac{{mass}}{{volume}} $

Complete Step By Step Answer:
The density is defined as the ratio of the mass and the volume of a body. The density of the human body is defined as the amount of the mass present in each unit of the body’s volume.
In order to measure the density of a human body, first of all measure the mass of that person in grams.
Then, fill the bathtub or a basin with water such that total submersion is possible, mark the initial water level when the person is not there in the tub, then when the person has put the whole body in water such that no more than the head of the person is out of the water, mark this new level with another tape. Remove the excess water with a measuring cup until the water level reaches the first tape mark. Use the measuring cup to keep a record of how much water is removed. The removed water gives the person’s body volume.
Convert the volume of the water into the unit cubic centimeters, then divide the mass and the volume to get the density in grams per cubic centimeters.
 $ density = \dfrac{{mass}}{{volume}} $

Note :
The density of any substance can be studied with reference to the density of the water whose density is $ 1g $ per cubic centimeter. The value of the density of the human body should be close to $ 1.1 $ . The reason for it is the presence of large quantities of water inside a human body that the density values are close.
