Formula used

Area: Length × Width
Volume: Area × (Thickness / 12)
Weight: Volume (cu ft) × 145 lbs/cu ft
Bags (80lb): Ceiling of (Volume (cu ft) / 0.60)
Labor Cost: Area × Rate × Finish Multiplier × Complexity Multiplier × Weather Multiplier
Crew Hours: (Area × 0.15 hrs/sq ft) × Complexity × Weather
Days to Complete: Crew Hours / (Crew Size × 8 hrs/day)
