    Design a function for an automated grading system that calculates the total wall area of a virtual cube-shaped learning module, where students must determine the area that would be covered by the four vertical faces only. The function should accept the edge length of the learning module as input and evaluate students' ability to correctly compute the lateral surface area, excluding the top and bottom faces.
