What’s the mass of each cube? Couldn’t find any info in Appendix A.
I couldn’t find anything either. I wouldn’t be surprised if they were weighted. That would be a very Vex thing to do.
the cad files show them being entirely hollow. I’m sure they are very light, like itz cones, maybe a tad bit heavier.
The official Cube weight is 285 grams. (~.63 lbs)
I’ve found they weigh roughly the same as a 2 ITZ cones if you want that as a reference.
