Population density= Total population divided by total area. Simply, if you have a scientific calculator, do the population over area.

The object's density = (its mass) divided by (its volume)
The formula for calculating density is as follows: density = mass/volume. Simply put, if you divide an object's mass by its volume, you will find its density. Density is the mass of an object per unit volume.
W = Volume x weight density
You can use 8.5 as Brass density and work out the weight
Mass divided by Volume = Density. Or use the displacement method for an irregularly shaped object.
Population density refers to the measurement of population in a given area. Its equation is given as PD = N / A, where PD stands for population density, N stands for the number of organisms and A stands for the area.
The definition of density is: Density = (Mass) divided by (Volume).A simple algebraic operation rearranges this definition to give: Mass = (Density) times (Volume)
Density or weight is calculated by mass/volume
