# What is the magnitude of the net charge enclosed by surface?

## Homework Statement

A closed surface with dimensions a = b = 0.302m and c=0.604m is located as in the figure.
The electric field throughout the region is nonuniform and defined by E⃗ = (α+βx2)ˆı where x is in meters,α=4N/C, andβ=4N/(C·m2).?
What is the magnitude of the net charge enclosed by the surface?

## The Attempt at a Solution

I tried to use E= (4+4x^2) and distribute the Epsilon naught value but obviously that is completely wrong. I am struggling and would appreciate any help that can be offered!!
