Calculate your own enclosure
Box volumes:
When calculating the inner volume of an enclosure you just multiply the
width (W) x height (H) x depth (D).
Use measures in dm and you will get the answer in liters.
A trapezoid box is calulated as this:
Vol=width (W) x height (H) x upper depth (UD) + lower depth (LD)
