The average density of the earth is, of course, the ratio of its mass to its volume.
The mass of the Earth is about 5.97x10^24 kg.
Although the earth is not perfectly spherical, it’s close enough (within 1%) that it can be modeled as such for the purposes of our calculation. Its radius is 6.37x10^6 meters.
The equation for the volume of a sphere is V=43∗π∗r3V=43∗π∗r3, so the volume of the Earth is about 1.08x10^21 cubic meters. Thus, the density of the Earth is about 5,500 kilograms per cubic meter, or, equivalently, 5.5 grams per cubic centimeter.
