A 48 inch table has 48x48 sq inches, which is 2304 sq inches, or 16 square feet. 300/16=18.75 Stick with 18 tables. However, you don't say if you want room for people to sit around the tables. My answer doesn't leave room for people to sit around the tables. If you want room for people to sit, then I would suggest that you try setting up one table with the chairs around it with people sitting in the chairs, then measure to see how much room it takes.
8 to 12
If it's 8 people per table, you would need 32 tables.

8 people comfortably. You can sit up to 10 if needed but less than 7 is too much room.
