i think these might be able to be used as sub cabinets,but my math skills stink.how do i get the volume of this cab.okay can someone do it for me.

I think you can calculate the volume by multiplying the height by one half the length of one side multiplied by the distance from a peak to the closest point on the opposite side.

You need to choose units of measurement to match the units you'd like the volume described in. ie if you measue in CM then divide the results by 1000 for litres. If you measure in inches divide the number by 12 * 12 * 12 to get feet cubed.

Half the base times the height times the length.

If you take two together, you got the area of a parallepipidum - a recktangle that's skewed. Google the area of a parallepipidum, and multiply with the height. Divide by two. Done.

1.332 cubic feet.

If you don't believe me, just pour sand into the box until it is filled and measure the amount of sand you have.

The area of a equal side triangle is hight squared divided by 2 - you get volume by then multiplying with hight (of the thing). Det area is 133 sq in which I derived with my 2D drawing program. den multiplied by hight -> 2127 cu in or 60 litres volume?

Could that be about right?
