Foam displacement equation: help!!

[Truefire]

Hey guys i am restoring a glasstream 17' bass boat and have recently dislodged the top portion of the boat, i have a lot of work to render on this top portion. I am curious to know if any of you guys are aware of the equation for the appropriate amount of foam sprayed underneath this portion of the boat to float it if needed.

Thanks so much for any advice or help you may be able to render in regards to this issue.

Sorry i don't have any pics of the underside of the top portion at this time. A lot of the original foam from the manufacturer is still intact and doesn't show any sign of ever being wet. Very rigid in all areas, some of this foam has came unattached in some small areas - just appears it just lost it's hold due to the top of the boat being exposed to the direct sun for so many years and the heat imposed thereon.

So as soon as i get this top of off the hull and flip it over i will be posting updated photos.

Thanks Chris
