How many boxes of spaghetti needed for Full Pan?

Please provide more information! I need to know:

* What size is the pan? (e.g., 9x13 inch, 12x16 inch, etc.)

* What is the serving size for a full pan? (e.g., 8 servings, 12 servings, etc.)

* What is the weight of a box of spaghetti? (This will vary by brand)

Once you provide this information, I can help you calculate the number of boxes of spaghetti you'll need.
