Physics Electric Flux Question?

total electrical flux = integral of the electric field over the closed surface of integration. Call this quantity PhisubE. Units are (V/m)*(m^2) = V-m. In the absence of polarization, Gauss' theorem is q = phisubE*εo = -5*8.85z10^-12 = -44e-12C = -44 pC. Answer is (d). Since total flux is already given, the geometry of the closed surface is immaterial.
