Those subs sound best in 1.5 cu ft sealed.
Just get the dimensions you have and multiply them Height x width x depth and remember to take the size of the wood that you are working with out of the equation. Divide that by 1728 and that will give you your cu ft. If you want you can even take out the size of the sub but it is not necessary. Just keep working with it until you get your box size right.
Tip: Do not build it in multiple of each other, example 10x 10x 20
or 7 x 14 or 6 x 12. Try to stay away from that.
Good luck.
If you have anymore questions let me know.
