63 Earths can fit inside Uranus.

Pretty obvious. Uranus is 4x the diam of earth and 4^3 == 64.
Sure if you to happen to know the 4x diameter
This is alt.astronomy.
which I didn't, and still why 64 and not 63. Also this analysis is only by volumes. I also asked about fitting spheres which is altogether different.
Sphere packing would be at least 25% less i.e. 48.
Now the problem becomes -- is 64 closer to 63 than 48?
