Why use "take" but not "need"?

Question

Why you think 'need' is more suitable here?

A: How long will it ( ) you to finish you work? B: Give me ten more minutes

need→× take→○

Answer 1

A: How long will it take you to finish you work?

is correct. The basic form is:

it will take you (five hours)

take in this context requires a direct object (you).

However, need as used here is intransitive, so you can't write "it will need you". Instead, you have to write:

How long will you need to finish you work?

The basic form here is:

You will need (five hours)
