How much cheese to buy for 120 hamburgers?

I need more information to give you an accurate amount of cheese! Here's what I need to know:

* What size are the hamburgers? (e.g., 1/4 pound, 1/3 pound, etc.)

* How much cheese do you want on each burger? (e.g., 1 slice, 2 slices, a small chunk, etc.)

* What type of cheese are you using? (e.g., American cheese, cheddar, mozzarella) Different cheeses have different weights per slice.

Here's a general guideline:

* American cheese: A typical slice weighs about 1 ounce. If you want 1 slice per burger, you'll need 120 ounces (or 7.5 pounds) of cheese.

* Cheddar cheese: A typical slice weighs about 1.25 ounces. If you want 1 slice per burger, you'll need 150 ounces (or 9.375 pounds) of cheese.

Once you provide me with the details, I can give you a more precise answer!
