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.
Multiply them: density*volume = mass
Volume = mass / density
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).
Density = (mass) divided by (volume)Mass = (Density) times (volume)
You can find the mass of the object by multiplying volume and density.
Density = mass/volumeMass = (density) x (volume)Volume = mass/density
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.
v= m/d v is volume m is mass d is density
The formula to find the density is d=m/v
You need also the mass of the material: volume = mass/density. After you measure the mass of the object, then divide by the density, to find volume.
You can't. In order to calculate a density, you need a mass and a volume.
