Needing to calculate total volume of house (conditioned AND unconditioned)

[mctabish]

I need to calculate how many gallons of rural reserve fire fighting water.

This is based off the volume of the complete structure.

How can I calculate this?

 

 

Thanks

Do you need the Attic Volume as well?

[mctabish]

Yes I do! 

Thanks

That makes it pretty difficult.  Chief provides some attributes which can be use in text macros for calculating volumes - but the roof shape can make it almost impossible to do that for the attic.  If the roof was all gable ends it would be possible but with hip roofs it's another story.
