What should the square inches of port area be if making a vented enclosure tuned to 32 Hz?

Question

If building a vented enclosure w/ an internal volume of 2.25 ft^3 and tuning to 32 Hz, what should be the square inches of port area?? (One 12" Alpine Type R.)

Also, would anyone be able to give me a personal experienced estimatation on the best shape/dimensions, for the enclosure, as far as length/width/height.. What works best in the type of enclosure I'm planning? ....With the subwoofer and vent/port both facing the same direction, is it better to be deeper or longer to accumulate to total volume of 2.25.....?
