Formula and assumptions

BEHIND THE NUMBERS

How this calculation works.

Material area = Σ((width − 2 × supplied gap)(length − 2 × supplied gap) − exclusions) × allowance; packs = ceil(area / pack coverage).

Material area = Σ((width − 2 × supplied gap)(length − 2 × supplied gap) − exclusions) × allowance; packs = ceil(area / pack coverage).Calculated with normalised units
