"the formula to calculate the volume of a triangular prism looks bloody horrible without half a bottle of wine,"
arrrh --- I had this absolutely brilliant iphone app. that did all sorts of weird volumes for shapes - - it was wonderful -
then the owner of the bloody thing didn't upgrade it to run on later IOS versions -- meaning, that if I find him - I am getting a contract out on him
I will have yet another look around and see if I can get a replacement - they are worth their weight in water -- or gold - or whatever it is you are trying to measure.
