I have heard this rule of thumb many times, but I personally think that is too small for adult boas.

The ideal ratio of cage floorspace to length of snake is different with every type of snake, but also with age. It is true that hatchling boas like to be kept snug, in which case this rule may be appropriate, but adult boas like lots of space.
