Sure - the "most precise" method will be experimentally test it in real... :) :)

Hm.. so.. probably the question is how much force can withstand the ball by contact-point forces... Is here a difference when the balls will be aligned in row (like vertical "oooooo" - 2 contact points only)? Any idea how to (approx) calculate the crushing force?

Not a homework, just thinking about variable buoyancy pontoon what will have a constant height above water level depending on weight. And are your'e sure about the topmost row? Because at some depth the balls must withstand the pressure of the water PLUS the pressure (forces) what are transferred via the contact points... (edited poping -> crunching - thx for the suggestion)

comment How to calculate the highest theoretical artificial hill?
I asked about the "soil" because i not want asking about the engeneering (buildings), but making a hill from "natural materials" like soils, sand, rocks and so on...

comment How to calculate the highest theoretical artificial hill?
@dmckee - yes, becase it is importatnt for "setting" the base of the hill height. From the above link, the highest possible hill is 49km high, but the question is - where is its "base"? (it is not the sea level).

comment How to calculate the highest theoretical artificial hill?
Yesss! The link is exactly for what I'm looking. Thanx. ;) (Only don't understand the 4.9km result - because in the earth Everest is 8+Km - but will study the article more deeply.. (4.9x10**4m is 49km)
