This article will quickly show you how to calculate the density of an object. Density is basically a ratio that tells you how much matter is packed into a particular space or object. The SI unit for density is kilograms per cubic metre (kg/m³).
Things You'll Need
In order to calculate density you must first determine the volume of the object using the following formula (if the object is square or rectangular shaped, if not a modification of the volume formula must be used):
v = l w h
v = volume (expressed in cubic units, such as cm³, or in mL)
l = length
w = width
h = height
Determine the mass of the object that you want to calculate density.
Now, use the following formula to calculate density:
d = m / v
d = density
m = mass
v = volume
The SI (International System of Units) unit for density is kilograms per cubic meter (kg/m³). For example:
you have an object with a volume of 225 m³ and a mass of 370 kilograms. Therefore:
d = 370/225
d = 1.64 kg/m³
