[akumaarchisci]

I need help on understanding how to calculate the buoyancy of undefined objects..and calculating bouyancy of things in general..

If you're looking for buoyancy formulas, then here is a good source:

Does anyone know if we have to calculate the values using significant digits?

density lab was a trial event inside of the 2018 Nat tournament. Is there any link I can follow to get my hands on that Density Lab trial test paper from nats or state. Cuz in the 2019 season Density Lab is no longer a trial event, it's a real lab event.

Nationals tests can only legally obtained by buying them from the soinc.org store. It's only $12 (?), and you get all of last year's tests, so in my opinion it's a pretty good deal. From my experience, very few state tournaments release their tests - at best they only hand back scored tests to the competitors, so I doubt you'll be able to get past state tests.
