mathematical formula for density. A rock has a mass of 20 grams and a volume of 4 cubic centimeters. The formula for calculating density is D MV 1.
The unit of land area should be square miles or square kilometers. Thus you see mass is on the numerator volume is on the denominator so we know that the greater the mass the greater the density and of course the greater the volume the lesser the density. R density kgm 3 or g cm 3.
Using the above formula 1 Dashiell et al.
Thus Population Density Number of PeopleLand Area. The probability density function PDF of a random variable X allows you to calculate the probability of an event as follows. The formula for calculating density is D MV 1. R density kgm 3 or g cm 3.
