Simpleminded question

[Dr. S. Shapiro]

Dear Colleagues,

	I have a plastic autoclave bag which consists of two thin plastic
sheets, 600 mm x 900 mm, fused along 3 of their four sides.  I need to
know the volume that this bag will hold when full.  Is there an easy way
to do this without filling it with water and weighing it?  Can someone please 
provide me with a solution?

	Kindly contact me directly at

Thanks in advance to all responders,
