Electric Flux Through a Face of a Cube

[Helmholtz]

Homework Statement

A point charge +Q is placed at the center of a cube. What is the electric flux through a face of the cube?

Homework Equations

Flux = Q/ε

The Attempt at a Solution

The answer is Q/(4ε), but I thought it should be Q/(6ε) which isn't even an option. I'm I crazy? Since there are six faces and all will get equal flux, and the total flux is Q/ε

 

[dx]

Q/6ε is correct.
