If you cut the bottom panel edge at 18 deg to match the angled side then measure the length of the cut you should be able to set a dado for the side piece that will match the angled cut on the bottom piece. Hopefully my explanation makes sense.

Cut the dado at an angle, unless I’m misunderstanding.

If the bottom rim of the box is flat you
can dry-assemble it and cut a groove
for the bottom on a router table with
a bearing guided 1/4” slotting bit. The
corners of the groove can be squared
up with a chisel. The groove in the
angled end will also be shallower unless
you switch bearings.

Why not just tilt the blade on the table saw. single pass with Dado stack. do a test on scrap first. Am I missing something?

Hah! I hadn’t even thought to use the table saw!

I’d been planning on using the router table to make all the dados, as two of them need to be stopped (the box needs to be joined using butt joints). But the angled piece will have it’s edges hidden, so the table saw will work. I’ll just need to make a few test cuts on scrap to make sure the router cut dados match up to the table saw cut ones.

Cut the dado at the 18° angle and bevel the bottom panel 18°.
