Calculated result

12 pieces per carton

2 × 2 × 3 layout

All orthogonal rotations permitted

100% rectangular volume fill

12.5 kg estimated gross weight

9 cartons for 100 pieces

4 pieces in final carton

1. Test all six orthogonal item orientations inside 60 × 40 × 30 cm internal carton dimensions.
2. Best permitted orientation: 30 × 20 × 10 cm → floor(60 ÷ 30) × floor(40 ÷ 20) × floor(30 ÷ 10) = 2 × 2 × 3 = 12 pieces.
3. Usable pieces per carton = min(12) = 12.
4. Volume fill = 12 × item volume ÷ carton internal volume = 100%.

This is a repeatable uniform-orientation rectangular packing baseline, not a proof of the global 3D bin-packing optimum. Allow for dividers, cushioning, tolerances, compression, closures and product-specific stacking rules.
