within what duration vs within which duration

Both "within what duration" and "within which duration" are grammatically correct, but they are used in slightly different contexts. "Within what duration" is more commonly used and sounds more natural in everyday language. On the other hand, "within which duration" may sound a bit more formal or technical. The choice between the two depends on the formality of the context.
