An arithmetic density is a population density measured as the number of people per unit area of land.
Density = Mass / Volume Rearranging this gives: Volume = Mass / Density Mass = Density × Volume
You have to know two out of three ... mass, volume, density ... then you can find the missing one. If density is missing . . . Density = (mass)/(volume) If mass is missing . . . Mass = (density) x (volume) If volume is missing . . . Volume = (mass)/(density)
The total number of objexts in an area
The integral of the density with respect to the variable against which the density is plotted, between the values at the ends of the curve. Since there is no information given as to what the density is plotted against, a more informative answer is impossible.
population density is defined as the number of persons per square kilometre of land.
Which South Asian country has the highest pupulation? The Anwser to that would be, Singapore. :)
Pop. density is the aver population per unit area. So to find P.D. divide population by area.
If you know the other dimension you can multiply it by the area to get the volume. Otherwise you can only get the area density (houses per square mile etc).
if you know the number of amperes and the cross sectional area you can find the current density
Density = Mass/Volume So you'd need the mass.
Density = Mass/Volume so Volume = Mass/Density. Therefore the Volume can be calculated. Volume = Area [of cross section] * Width So Width = Volume/Area.
To find the population density, you take the population and divide by the area. Let us use the United States as a quick example: Population: about 313,000,000 Area: 9,826,675 km2 Population density then equals about 32/km2.
Count the population (a census) and have surveyors establish the total area in which this population lives. Divide the population by the area to find population per unit area (density).

The population density of the US is 32/km2. To find the population density of a place, you divide the total population by the area of the place. US - Population : 313,839,000 Area : 9,826,675 km2
