Box Fill

[Therealcrt]

I will have two sets of 500 KCMill AL with 2/0 AL ground stabiloy MC Cable entering into the back of a junction Box. Out of the bottom of the junction box I’ll have 2 3” EMT conduits piped down about 10 feet into the top of my panel. With the same wire configuration, except THHN. What would be the correct size Junction box I need to make those connections length, width, and depth right now I came up with a 24 x 24 x 6“ junction box

You didn't say how many conductors are in each conduit, or better yet, what size conduit would the conductors fit in?

Sorry there 4 500’s and 1 2/0 AL in each conduit

That will work, but you might consider using a wireway.

The length is good
Depth meets code. (A little shallow for my preference)
The width seems large but is fine.
