    Design an algorithm for the adaptive learning system that calculates the total area of paint needed to cover the four vertical sides of a display cube, given the cube's edge length, to help students visualize lateral surface area concepts. The system will use this calculation to generate practice problems of increasing complexity based on student performance.
