Morphology
how + long + be + a + piece + of + string
Although the constituent words are literal and familiar, the phrase functions as a rhetorical proverb meaning 'there is no precise answer' and this figurative usage cannot be derived from the literal question about string length. Recognizing this non-literal, conventionalized use requires prior exposure rather than compositional inference, so it is unpredictable for a B1 learner who only knows the parts.
Etymology
How long is a piece of string gives a simple picture: a piece of string can be any length, so you cannot say its exact size without more information. So people use it to mean 'it depends' or 'there is no simple answer'.
