If I remeber right....

Length x width x height (in inches) divided by 1728 = cubic feet.

So, 40.9(W) x 33.3(D) x 35.6(H) divided by 1728 = 28.059104166666666666666666666667

Is that internal dimensions or external dimensions? If it's external, take into consideration the thickness of the wood. Is there any bracing on it? If so take that also into consideration. Are you building your box taking into consideration woofer displacement and port displacement?

Eco, but that it woudl mean that the box is about 1.7 cubic feet, Which would make sence.

Lanman, I am buying the box, not buliding it. Those were the dimentions I was given so I am assuming that its the exertnal dimentions. I hope it is because I need somethign 1 cubic foot if i want a sealed box, whcih I do

If those are external dimensions the box is 1.225 cubic feet internally, before woofer displacement and all that other good stuff...

I didnt even think of speaker displacement, thanks guys! I think i am going to go with this box. I need 1cubic foot sealed for my sub, and with the speaker displacement that shoudl be pretty damn close
