    Design a function to calculate the total monitoring coverage area for a fraud detection system that uses cube-based visualization, where each face of the cube represents a distinct transaction monitoring window, and the length of the sequence determines the cube's dimensions. The lateral surface area of this monitoring cube will determine the effective transaction pattern surveillance capacity, excluding the top and bottom faces which represent the start and end of the monitoring period.
