I am having trouble with this. I have the outermost integral from 0 to c the middle one from 0 to b and then the inner from 0 to a with the order dx dy dz. I am not getting close to the answer that I am suppose to. It could be just because this is the very first triple I have tried to solve but,..... Thanks to all who help on this forum. Frostking
