fill it up with sand ....then pour all the sand into a large square shaped box...then it will become as simple as measuring the volume of sand in the square box...

**Trunk 0-1000.................. 151.3**

**StreetBeat 2................... 145.6**

## Re: Finding Volume of an Odd-Shapped Box?

See the plan was to figure out the volume

**before**I built the box.

Anyone else? Or should I just give up a build a rectangular box?

## Re: Finding Volume of an Odd-Shapped Box?

Divide the box into sections, taking the volume of each part and adding them together.

assuming that is a right angle you figure the full square and divide by 2.

If its not 45° or are not very diligent at math then fill it up with sand. Or packing peanuts will also give you a descent guestimation.

He wants to calculate before making it, guys..

## Re: Finding Volume of an Odd-Shapped Box?

I think making an enclosure like that would be a pain in the *** with all the angles, and all the trig involved in making the cuts, what about the port? The bottom of the port will be longer that the top, what will you do to compensate? I think your better off with a simpler enclosure, take Calc III, you would be able to figure out the volume, I know we learned how last semester, im sure if I had the eqn's of the odd face, I would be able to figure it out, but that requires to crack open my book.

well what subs will be in it? and if you don't make it slant back it would be easier to calculate/build

Break it up into different shapes and calculate those shapes volume, then add.

you could also go back to 8th grade and relearn math
