Need Help With Multiple Ports

[Einzee 10+ year member]

My favorite enclosure calc. says that one 3" round port needs to be 4.75" long. When I input two ports... it says port length = 12.16 inches. Does that mean that each port needs to be 12.16" or do I make 2 ports and split them for a grand total of 12.16"? Am I trying to make a total of 12.16" for two ports or does the length of both ports need to be 12.16" for a total of 24.32"?
