Formula

Void carton = carton_volume-product_volume; Filler = (carton_volume-product_volume)*quantity*expansion; Bags = Math.ceil((carton_volume-product_volume)*quantity*expansion/bag_volume)

Worked example

Inputs

Carton volume: 30 L
Product volume: 18 L
Quantity: 50 cartons
Expansion: 1.2 ratio
Bag volume: 100 L

Expected results

Void carton: 12 L
Filler: 720 L
Bags: 8 bags
