Since nobody else here can seem to understand, let alone answer, what's
basically a simple question, might I suggest that you answer it
yourself? Assuming you have the trays you want to use, just fill them
with water to the minimum height you think you'll need, then pour out
the water and measure it. (If you don't actually have those trays, then
you'll have to do a volume calculation, based on the area of the tray
multiplied by the height of the developer solution, which you can again
determine empirically.)
This is what you wanted to know, right?
