4 people per large so 10 pizzas
I used to say 4 people for 1 large pizza 🍕 so based on that 10 pizza. (more if all guys, less with women, more with adolesence boys, less with girls)
Each of you get two slices so 40 times 2 equals 80 so five pizzas 10 pizzas
I'm guessing between 10-12 pizzas. Really depends how much people eat.
