Maybe a lot less tedious than counting squares, if reliable.

A lot of paint programs (Photoshop,etc) can do what this does.
Looks like a nice program to use though.

Yeah it's amazing what can be done with basic computer skills and even with a simple spread sheet. I know because I can't do it and when someone does I am amazed.

Old drafting/engineering trick:
Make your sketches or make an actual cutout of the cross-section.
Weigh the cutout.
No computer required
