Formula:
Total Wall Area = (Wall Length × Wall Height × Number of Walls) - Total Openings Area
Where:
- Wall Length: The horizontal measurement of a single wall (e.g., 12 feet).
- Wall Height: The vertical measurement from floor to ceiling (e.g., 8 feet).
- Number of Walls: How many walls of these exact dimensions you have (default 1).
- Total Openings Area: The combined area of all doors and windows to be subtracted (e.g., 21 sq ft for a standard 3x7 ft door).
