I just meant a room with 8 ft cielings and 12 ft wide and 24 ft long is not perferrable or 8x10x16.
I was told and found that a roomwith no common denominator was best as it 7x13x19
If you were to want a room to be roughly 8x10x16, but want to avoid any of them being divisible by the same number then you just have to make sure to find the two closest primes for the length and width, since the height of the room would probably be the one that you wouldn't want to change if you don't have to. So do 8x11x17. There is no need to have them all as prime numbers.
