A cube of side l-55cm is placed in a uniform field E= 7.30 X10^3 N/C with edges parallel to the field lines.

a. what is the net flux through the cube?

b. what is the flux through each of its six faces?

Face 1 perpendicular to E (field lines enter the cube)

Face 2 perpendicular to E (field lines exit the cube)

Face 3 parallel to E

Face 4 parallel to E

Face 5 parallel to E

Face 6 parallel to E

Now...it might just be throwing me off...but I THOUGHT (which i could totally be wrong) that the parallel sides will have a flux value of zero because E is not entering or exiting those areas.

However..I could be completely wrong because it seems I am teaching this problem to myself at the moment...but I am still lost on how to find the net flux and when it enters and exits...

OH...I have an equation that the electric flux = EA cos (theta) I substituted the values in...figuring area as 3025 cm^2 and then converting to m^2 and subbing everything in the equation but I am doing something completely wrong....

HELP Please!
