2. Mass (of nucleus) is proportional to volume.

3. Volume can be determined from cross-sectional area.

If this is the case, then is E=mc^2 equivalent to kE=(pi)r^2 where r is the radius of the nucleus and k is some constant?

What's the idea to measure volume of as a cross section anyway?

Volume of n-sphere can be easily calculated without any cross sectional area using formulas.

Cross section of 4D objects is 3D object.

I have no idea how to calculate mass-radius relationship for nucleus, it's difficult because it's a compound, but for example mass of electron = coupling * Planck's mass * Planck's length / classical electron radius
