comment How can a piece of A4 paper be folded in exactly three equal parts?
I think this is a description of how everyone already folds paper, rotated 90 degrees.

I just tried this experiment. 64 trials, only one of which resulted in 300. I know the number of trials is small, but the average was 309.75.

comment A “simple” 3rd grade problem…or is it?
This answer is cute, but in my experience, cut rate is limited by the power input to the blade. Assuming the student tried as hard as possible for the first cut, cutting with two blades at once would not speed the operation.
