Hello:
This has to be possible, since some manufacturers of trash can liners are able to do so.  They list a description of their liners with length and height that equals x number of Gallons.  Besides, since they list this data, presumably they know it.  
I have customers which will order liners, but have no idea of the gallon capacity with the linear dimensons.  
I have searched to the nth degree without any results.  
Can anyone educate me with a formula or chart to solve this issue?
Kindest Regards,
tcw
