Packing-volume utilization calculator
A box is never perfectly full; the usable percentage accounts for gaps and protective material.

- Geometric box volume

- Usable volume per box
- 72.0 L
- Usable spare capacity
- 38.0 L
Show the working
- Inside box length = 60
- Inside box width = 40
- Inside box height = 40
- Total item volume = 250
- Usable box volume = 75
- Geometric box volume = 60*40*40/1000 = 96
- Usable volume per box = 96*75/100 = 72
- Boxes required = ceil(250/72) = 4
- capacity = 4*72 = 288
- Usable spare capacity = 288-250 = 38
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- box litres = length x width x height / 1,000 when dimensions are centimetres
Irregular objects, padding and weight limits can require more boxes than volume alone predicts.
