What is the net flux of the uniform electric field of the above question through a cube of side 20 cm oriented so that its faces are parallel to the coordinate planes?

Explanation

To find the net electric flux through a cube of side 20 cm in a uniform electric field, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Electric Field**:
The electric field is given as \( E = 3 \times 10^3 \, \hat{i} \, \text{N/C} \). This means the electric field is directed along the x-axis.

2. **Determine the Area of the Cube Faces**:
