That's a trapezoid.

Is it, though, if both triangles on each side are the same angle?

It's also a 3-dimensional plastic part, trapezoids when I was learning geometric
drawing and perspective were always 2-dimensional shapes, and would need to have
their cubic range calculated by dividing them up into their component geometric
shapes.

Thank goodness we have computers nowadays, if we still had to manually calculate
the 3-dimensional cubic area that a LEGO part occupied, I doubt we'd have
had anything more complicated than bricks or plates on this site.



Cheers ...

I must have grown up in the dark ages(before computers).

We calculated the cubic volume if a trapezoid with this formula:

-- Volume of a trapezoid = 1/2(B1+B2) x H x L
