Measure the mass first i.e. Body weight , then measure the volume of the body by immersing in known quanity of water contained in a tub, measure the quantity of water displaced, which provides the measure of volume . Divide the Body weight by volume of the body.
Density is a weight per unit of volume such as pounds per cubic foot or grams per litre. You need to weigh a known volume of the substance you wish to determine the density of. Some engineering handbooks have charts for densities of common materials such as water, concrete, sand, steel, glass, etc;
D=M/V
Take their mass (weight in kilograms) divided by their volume (put them in a tub or barrel marked for ever so many liters, put in water, get them to submerge fully, and see how many liters it goes up.) The result will give you their density. Most humans will be slightly less than 1. A fatter person will generall be a bit less.
You would need to make generalizations for each portion of the body, then find each volume. For example, call each leg and each arm a cylinder, your head a sphere, and your body a rectangular cube. Find the volume for each part using average heights and/or diameters. Then, divide the mass (kg or lb/(32.2 ft/s^2)) of the whole body by the volume you found. Voila, you have a rough density.
If you know calculus, you can be a little more accurate by doing a triple integral where the radius changes from the radius of your ankle to the radius of your thigh. Another way to look at it is if you dunk yourself under water and can compute the volume you displace, then weigh yourself, you can calculate your density D=m/v
According to wikipedia (See related link below), density is 1010 kg/m3 = 1.01 g/cm.
Please understand that this number is good for calculations and estimations but not real life because it averages all the densities of skin, bone, blood, brain, etc..
I did this in science class. Okay u put the person in a type of dunk tank, and measure the amount of water that comes out of the tank when they go in it. then of course use the equation density=mass divided by volume and yeah there the goo.
Immerse the body in water, measure the displacement, weigh the body divide the mass by the volume. (The density is almost 1) and depends on if you count the air in the lungs as part of the body or not)
Take the total mass and divide by the the total volume
you get the density
well that's sort of it but how do you know your mass and volume?
how do you calculate density
Density is calculated by the mass divided by the volume.
Density is a very important property which can be used to identify a substance. We can calculate Density by dividing mass by volume.Density is the measure of how compact something is. To calculate density, take the mass of the substance, and divide it by the volume of the substance.
no the mass of the object would not even be able to calculate the measurment of density
Can't be answered, you need both weight and volume to calculate density.
How can you calculate surface density if the volume density is 1.4 g/cm3
how do you calculate density
It means: * Calculate the density of an object * Calculate the density of its pieces * Compare
volume/mass= density
density = mass/volume
The density can be measured experimentally.
density = mass/volume
The shape of an object is not enough to calculate its density. You also need its mass and then Density = Mass/Volume.
Mass and volume are needed to calculate the density of a graduated cylinder.
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.
density = mass/volume
== Density== Mass/Volume =) ===
