Calculus? Hmmmmm.
Isn't the flux coming out equal to the charge in (divided by permittivity)?
Exactly what is Gauss' Law? http://hyperphysics.phy-astr.gsu.edu/hbase/electric/gaulaw.html
A point charge of 1.8uC (microcoulumbs) is at the center of a Gaussian cube 55 cm on edge. What is the net electric flux through the surface?
