Karol Brzezinski proposed the following answer:
Hi,

The size of the clump is adjusted to balance the mass (~volume for the same material) of the replaced sphere. Every figure with the same mass would stick out of the sphere. You have a relatively flat shape, hence its dimensions need to be much larger than the sphere.
For sphere with diameter D:
Vs = pi*D^3/2
For a prism (more or less similar to your clump, with edges equal to A, 4A/9, and A/9:
Vp = 4*A^3/81

So if Vp=Va
A/D = (81*pi/8)^(1/3) 


So the clumps should be more than three times longer than spheres.

Cheers,
Karol
