1. ## Box DIM. airspace, am I right?

20 " width x 8" bottom depth X 3" top depth X 18" heigh, using 3/4 MDF this would come out to 1.450 right? Its like a slant box ona truck

2. I came up with 0.84...

3. I came up with 0.707...

Uh oh...

- Steve

4. [(20-1.5)*(5.5-1.5)*(18-1.5)]/1728 = 0.706 ft^3

the 5.5 is the average of the bases since it is a trapaziod.....thats what i get?

5. Ive got 0.83908cuft

6. Hey woodmister, those calcs are awsome thanks. Everyone else thanks for the help, i guess i was way off, first time i did it :-)

7. I like wood misters calculator so much better, the one u had slipknow, look at what it measures, where the side wood ends ont he bottom peice. Like wood mister's calc measures the whole bottom as urs only measure the bottom where other wood isnt touching

8. yeah....but you want internal dimensions right?

9. ok dont believe me...do on a calculator

10. Yeah I want the internal volume but I gave the external dimensions, so doesnt the calc take out the 3/4 all the way around? I dont know i give up lol ill jus go wit wood mister

11. 18.5x4x16.5/1728 go put that in a calculator

12. 20 " width - 1.5 = 18.5
8" bottom depth - 1.5 = 6.5
3" top depth - 1.5 = 1.5
18" heigh - 1.5 = 16.5

18.5 x 4 x 16.5 = .7065

What sub is it? The box can be a lil big, it can produce more bass...

13. anybody look at mine...good old fashion mathmatics....its just the volume of a trapazodial prism....still sticking by my 0.706 messurement.....since a few others got that as well....im pretty sure it is correct.

14. Count me as another one that got 0.7.
