Imagine that we know the volume of the Earth, which is  1.08 x 10**12 km3
And we model the Earth as a perfect Sphere.
We know that the volume of the sphere is V = 4/3 * pi * (r**3)
We can solve for r......................r = cube root((V*3/4)/pi)
r = 6364,71 km , which is a good approximation for the radius of the Earth!
