🧮 SQM Calculation Formula

The application uses specific formulas based on Flute Type:

For C Flute (C32, C40):

• Sheet Length (L): 2 × (Length + Width) + 15 (mm)
• Sheet Width (W): (Width + Height) - 10 (mm)

For BC Flute (BC40):

• Sheet Length (L): 2 × (Length + Width) + 11 (mm)
• Sheet Width (W): (Height + Width) - 16 (mm)

Area Calculation (All Types): ((L × W) / 1,000,000) × 1.08 (Includes 8% Wastage)
