    Calculate the total surface area requiring moisture-resistant coating for standardized loan document storage boxes, where each box is a perfect cube with sides equal to the standard document length measurement. The surface area calculation will determine the amount of protective sealant needed to safeguard sensitive loan documents stored in the bank's secure vault.
