Number of bags = 105/(12 x .8) = 10.9375

I believe that the rubber band has helped society in a number of ways, it is also my personal belief that deep down we all want to be rubber bands. the ways rubber bands have effected society are that people like stretchy things, so rubber bands relieve stress by people stretching them. also I have heard that wearing a rubber band around your shoulder when you have very smelly arm pits it will remove at least part of the smell. also some kung-fu masters agree that wearing a rubber band on each ankle and wrist it will greatly help your kung-fu skills develop to the master level, so it helped ancient Chinese society develop, it is also rumored that the samurai used rubber bands to hold together their armor. another thing that many agree on is that if you cover a fruit tree with rubber bands it will bear fruit at least twice the size. that is all my knowledge about rubber bands, but with some good research and effort you can become a rubber band master like myself

the amount something weighs, depends on the volume of it you have and how dense it is. Though glass will have a fairly consistent density, in your question you only mention the thickness, if that glass were to cover an area of 50 square miles it would weigh more than if it only covered an area of 10 square millimetres.
