The basic objective in choosing room dimension is to have the frequencies of the room mode evenly spaced. There is no perfect way to do this and there are several suggestions below. (You can google and find some info on each, or just calculate the room modes yourself and see how they are distributed.) Of course in real life rooms aren't perfectly rectangular, walls aren't perfectly rigid, etc, etc. The most important thing is to avoid 1:1, 2:1, and other ratios involving low primes.
Sepmeyer Room A: 1.14C x 1.39C x C (9'1" x 11'1" x 8')
Sepmeyer Room B: 1.29C x 1.54C x C (10'4" x 12'4" x 8')
Sepmeyer Room C: 1.60C x 2.33C x C (12'10" x 18'8" x 8')
Louden 1.4C x 1.9C x C (11'2" x 15'2" x 8')
Volkmann 1.5C x 2.5C x C (12' x 20' x 8')
Boner 1.26C x 1.59C x C (10'1" x 12'9" x 8')
