i was wondering if anyone knew how to calculate the volume that a 19 1/4 inch long 2x4 would take up inside a box for a brace, any help would be great thanks

I would assume you would subtract its volume from your box volume.. so..

V=LxWxH..

19.25*2*4=153in^3

soo..

153 (in^3) = 0.0885416667 cu ft

I think thats right.

Turn the lumber into cubic feet/inches and subtract it from the cubic feet/inches that you have for your box? Not too sure though...

Wow. Someone forgot basic geometry.

And even then, the one that gave the math is wrong.

2x4s are not 2"x4". The OP will have to measure the 2x4 to find it's actual size, but generally it is 1.5"x3.5". Multiply these two numbers and then by how long the piece is. Subtract this number from the volume of the box. Remember to convert units. :)

Do they teach math in school these days? This is middle school stuff.

The answer is 0.05848524306 cubic ft.

A little exaggeration aye? 3d geometry is high school.

Whats wrong with using a 2x4 as a brace? Building my first box and about to put one in there... maybe

Metal is more of my thing, not wood. Even still though, the difference between my math and the 'correct' math is very small.

I'm still learning with math and I've struggled with it for years.

I dobut one '2x4' brace would impact your boxes volume enough to notice at all, it seemed rather miniscule.

If you want to get really precise, you'll take the rounded edges into account.
