In mathematics, powers of 2 and 3 are often referred to using "square" and "cube" terminology: a "number squared/cubed", the "square/cube root of a number". But then you have "quadratic and cubic" Beziér curves. Why is the confusing term "quadratic" used when "squaric" would be more consistent? Alternatively, why isn't the term "hexatic" used instead of "cubic"?
