Is this stand design ok for a 20g

Sorry for the crappy drawing but I’m looking to do my first DIY stand for the Waterbox 20g cube, will this design hold up and work for that size tank? Also wondering if I’ve picked the correct materials. Any advice or criticism would be welcome thank you.

Turn the boards so the top narrow face is up. The wide direction should be the one resisting the weight. The board is about 4X stronger that way.
