Tubas are conically tapered, and this taper does all sorts of things to the resonance of the tubing. So, yes, the lengths are approximate. I measured two Bb tubas of similar overall size, and one's open bugle was 209 inches, and the other one's was 215 inches. Interestingly, the instrument with the shorter open bugle has a much smaller bell. So, the shapes causes variabilities that go beyond the diameter of the bell.

It could also mean that my measurement methods were no good.
