Cubic foot of a box?

[laser1984]

How do u figure the inside cubic feet of a 12x12 box?...

That is 3/4 thick with carpet

[ultimate157]

Well, you need a 3rd dimension.

those two would be internal dimensions of 11.25 x 11.25 ... whats the third dimension ?

[mtlhead]

12x12x??

Volume = HxWxL

we need one more dimension

[laser1984]

Wht would be the 3rd?


Spkr. Displacement?

[mtlhead]

Height, width, length

[mtlhead]

have u taken math before??

Volume = Height x Width x Length

[Mitch86]

Length x width x height minus wood thickness divided by 1728 = how many cubes you have internally.

[laser1984]

Height 12 inch
Width 12 inch
Length 12 inch

[mtlhead]

i get .67, anyone else?

[Mitch86]

That should be correct.

But, I think it's better that the original poster learns to do this himself.

[ultimate157]

10.5 ^3 = 1157 / 1728 .669 cubic feet.

I always ****ing forget to double the outside walls.

[mtlhead]

true so heres what i did:

12x12x12 is your outside dimensions

because you have 3/4" wood, you need to acount for that, so subtract 1.5" from each side and thats the internals

now multiply those and divide by 1728, how many cubic inches are in a cubic foot.

that gets u your volume

instead of editing, i will just say i am an idiot! lol, same as ultimate. double walls

[mtlhead]

11.25 ^ 3 = 1423 / 1728 = .8239 before woofer displacement.

dont u have to subtract 1.5 from each dim because each side has 3/4" of wood on it

[Mitch86]

That's what I was thinking also.
