How do you figure the cubic feet size? Especially for odd shapped boxes?

L x W x H... divide that number by 1728 (a cubic foot) if your dimensions are inches.

Did you never take geometry?

I took geometry like 4 yrs ago, u think I can remember what I learned?

I do remember some things, just not the formula for volume.

So you find the dimensions, multiply them, and then divide by 1728 to find the volume?

What about boxes with a slot port, do you add the port in, or not?

I want to find the net size. How do you do that?

I want to be able to do these calculations myself, so I want to learn it.

Right now im going by my current box, and when I did the calculations, it came out 6.6--- cubic feet. But the box is 4 cubes.

If my dimensions are

D- 48"

W-48"

H- 17"

I got in total 22cubic ft (without port displacement). Is this correct?

Yes, it would be 22.6 cubic feet if those are interior dimensions.

If those are exterior then it would be ~19.4 cubes.

So how do u figure out the port cubic size to subtract it from the total of the box?

The exact same way... Length x width x height of the port.
