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).
You cannot. If you are given the density, the volume of the object, and the area over which the object rests, then it is possible to find the pressure. If density is "d", volume is "v", and area is "a" then pressure p = (d x v x g)/a where g is the acceleration due to gravity.
Multiply them: density*volume = mass
Density = mass/volumeMass = (density) x (volume)Volume = mass/density
You don't need to find it. From what your question states the area is already given to you.
Density is usually defined as mass per volume - with units given for both measures. There are instances when planar density (eg grams per square metre for paper) or linear density (kilograms per metre for beams) are used but they are less common. In any case, without units the calculated number is meaningless.
Density = Mass/Volume So you'd need the mass.
Strictly speaking if the density is given then you don't need to find it.
Density = Mass/Volume so Volume = Mass/Density. Therefore the Volume can be calculated. Volume = Area [of cross section] * Width So Width = Volume/Area.
-- Find out the population of the area. -- Find out the area of the area. -- Divide the population by the area. The result is the population density of the area.

population density
The formula to find the density is d=m/v
Multiply them: density*volume = mass
You can find Dynamic pressure by using bernoulli's equation. P = (density * velocity^2)/2
Density = mass/volumeMass = (density) x (volume)Volume = mass/density
You can find the mass of the object by multiplying volume and density.
