Is "I would like to know" informal? [closed]

I'm sending an e-mail to schedule my internship. Is this sentence, "I would like to know if I can cover up Thursday's by working extra hours on other days." sounds informal?

Is there a better way to ask this kind of question in a nicer and formal way?

Thanks!

Solution 1:

It looks formal enough; the context needs some clarification. Remember, the magic word never fails:

I would like to know if I can cover up Thursday's hours by working extra hours on other days, please.

And turning it into a question makes it even better:

Would you please let me know if I can cover up Thursday's hours by working extra hours on other days?

Then, it's formal enough for your internship.

Solution 2:

It's not too informal for an email, but make up may sound more natural than cover up, since make up suggests restore while cover up suggests conceal.

Solution 3:

"I would like to know if/whether..." sounds kind of awkward and unnatural in this particular context.

Instead, I'd suggest being more direct, yet polite, and say:

May I make up Thursday's hours by working extra hours on other days?
