Calculating Flux on a Rubik's Cube with a Point Charge at the Center

[ab23]

Each sub-cube of the puzzle has edges 3.0 cm in length. A 8.0 nC point charge lies at the puzzle's center. What is the flux through the one face of the sub-cube labeled with the logo?

Note: Its referring to a Rubik's Cube that has 8 sub cubes

I used the equation where i divided the charge by the permittivity constant and then further divided it by 24 but that didnt work.

Yep - that was a reasonable thought, but it doesn't work. The problem is that the faces are different distances from the source so they experience different field strengths and subtend different angles. I think you'll have to do this the hard way, actually computing the surface integral

In any case, this probably belongs in one of the homework forums... Moving it now.
