Boxes = room area x waste factor / box coverage, rounded up.
Actual conditions, local rates, product labels, and contractor recommendations can change the final quantity or cost.
Example Calculation
240 sq ft with 10% waste and 22 sq ft boxes needs 12 boxes.
Tips

- Use more for diagonal layouts.
- Confirm box coverage on the label.
