An electric field given by vec$(E)=3\mathrm{.}0$hat$(i)-8\mathrm{.}7(y^2+8\mathrm{.}5)hat(j)$ pierces the Gaussian cube of edge length $0\mathrm{.}450m$ and positioned as shown in the

figure. $($The magnitude $E$ is in newtons per coulomb and the position $x$ is in meters.$)$ What is the electric flux through the $($a$)$ top face, $($b$)$

bottom face, $($c$)$ left face, and $($d$)$ back face? $($e$)$ What is the net electric flux through the cube?
