Why would you not put them on their side and stack them like hard drives? You'd get way more density that way then trying to figure out how to make it fit in 1u for no reason. You could even stack multiple rows deep to get more density.

19 mod 1.4 = 0.8, 0.8 x 7.7 = 6.16 in^2

19 mod 7.7 = 3.6, 3.6 x 1.4 = 5.04 in^2

Presumably the greater waste of bottom side down is in higher number of shelves?
