thanks for reading the problem confuted, note the toothpaste bottle is almost empty, we have to find the REMAINING amount of JUST THE TOOTHPASTE (therefore submerging won't work), but the problem at hand is discussing methods people have already tried to get the last bit out of toothpaste out of the bottle, NOT finding the volume, lol.

so to answer your quote

Trying to find the volume of a tube of toothpaste, eh?
no, I am not currently on that yet
