Let the area of the back surface of the trapezoidal box in Figure 24.22 be \(1.0 \mathrm{~m}^{2}\), the magnitude of the electric field be \(1.0 \mathrm{~N} / \mathrm{C}\), and \(\theta=30^{\circ}\) for the front surface.

(a) What are the magnitudes of the area vectors for the front and back surfaces of the trapezoidal box?

(b) What are the electric fluxes through the front and back surfaces?
