Calculation
Earth is an oblate spheroid, resembling a sphere flattened at the poles.
The volume of an oblate spheroid is
- <math>V = \frac{4}{3}\pi a^2 b</math>
where <math>\pi</math> is the mathematical constant pi, and <math>a</math> and <math>b</math> are the equatorial and polar radii.
Substituting a = 6,378,135 m and b = 6,356,750 m, we get the above Earth volume.
