Question: Given to me, by a friend:

* You may use any basic operation. And others, such as square roots (the symbol), factorials, etc. Any operation is allowed.
* Just two threes, though. You can't raise a three to any digit other than three, etc.

Any out of the box, non-mathematical solutions are encouraged.

PS- Wow! That's an amazing number of responses! Quite a community, here.

EDIT: @CameronWhite and @Yly have provided, perhaps the most elegant answers. And basis your votes, I'm going ahead to mark @Cameron's answer as accepted. No issues, I hope. Although, I did think @KeyboardWielder's answer was rather crafty. And @dcyfj... Well, that would have taken some time. Awesome answer. This really isn't an edit, is this?

EDIT: Perhaps I should have specified the level of out-of-the boxness allowed. Forgive my mistake. This was, my first post, and I was surprised by the number of answers. Thanks for taking the time.

Answer: 
Since the puzzle oddly and specifically mentions the **symbol** for the square root, I used this:

but rotated and reflected it giving:

As you specifically said to think outside the box, I drew a box, and two three's (one Roman numeral and one Arabic numeral) which extend "outside the box". As my answer note that they divide the box into 20 (yellow regions).

Therefore:
Box / two three's = 20
