A cube has sides of length L = 0.370 m. It is placed with one corner at the origin. The electric field is not uniform but is given by E=-4.33xi+2.32zk.

Find flux through every side of the cube.

2. Relevant equations

Flux=EA

3. The attempt at a solution

There is no y-component to E, so I figured there wouldn't be any flux through the sides perpendicular to the y-axis.

For those faces perpendicular to x-axis:

the field is pointing left, so for the face on the left, the flux would be positive (it's leaving the face) and for face on the right, the flux would be negative (it's entering the face).

Flux (left face) = (0.37^2)*4.33=0.593

I used similar approach for all other faces, but that's wrong. Then I saw that it's -4.33x *i. So does that mean I have to multiply by 0.37 again? Because that's apparently wrong too.

Thanks, help will be really appreciated.
