Answer

$\Phi = 0$

Work Step by Step

$E = 4.0 \hat{i}-3.0(y^2+2.0) \hat{j}$ Note that the electric field only has components along the x axis and the y axis. The component of the electric field along the z axis is zero. We can find the electric flux through the top face: $\Phi = E~A~cos~90^{\circ}$ $\Phi = 0$
