    Write a function to calculate the total exposed monitoring surface of a transaction cluster block, where each block's side length represents the standardized transaction grouping parameter, to determine the pattern detection coverage area for fraud analysis. The exposed surface area excludes the top and bottom faces of the block, as these represent internal transaction boundaries not relevant for cross-account pattern analysis.
