Working out volume and area

I've just designed a studio that I think would be worth while. To confirm my suspicions I need to work out the RT60's for each room. The only problem is, my rooms are completely abnormally shaped! How would I go about working out the area for the floor and the then the total volume of the room? I could break each room up into 4 sided figures. What's the equation for the area and volume of these types of oddly shaped figures? Anyone? Thanks a lot for the fast answer last time! :D

Rather vague, question. Where dis you get 4 sided figures from? Are the rooms varius combinations of rectangles? Then yes, 4 sided figures. IF not then the usual surveying method is is use 3 sided (triangular) analysis. Andre

The problem with writing volume formulas for irregularly shaped rooms is the fact that there's an infinite variety of infinitely shaped rooms. :wink: Yes, trianglular prism analysis will work. If the angles involved aren't horribly steep I woulkd probably just use rectangular estimation.
