  Maybe, maybe not.

  Solid objects aren’t always stronger, strangely enough. I’m no mechanical engineer, so I can’t explain it. I assume it has to do with how stress is tranferred.

    If there are bending forces on the object, the middle of the structure basically doesn’t add any strength. If it’s in tension or compression, it does.

    For this challenge, with the 50g weight limit that has bending forces, a hollow object is always stronger. If he filled in the middle, it would add more weight for very little additional strength.

      What about a honeycomb-like filling, mostly open, but with walls strengthening it?
