    Design a function for the geometry learning module that calculates the total area of the four side faces of a virtual 3D cube (excluding top and bottom faces), where students input the cube's edge length in standard units. This calculation will be used to assess student understanding of lateral surface area and provide appropriate follow-up practice problems in their personalized learning path.
