geometry

$begingroup$ If I'm understanding you correctly, their are two pairs of trapezoid faces opposite each other (i.e., in the image of the yellow skip, the left face isn't actually 90 degrees vertical [even thought that's what it looks like], it's leaning to the left a little). In that case, I don't think there's a simple calculation. You'd have to break the whole thing up into simpler shapes and Get price
