Packing models definition
Packing models definition
Mathematical representations for arranging items in limited spaces
Formula: Number of containers needed
Formula: Number of containers needed
Total items ÷ Items per container
Rounding rule when determining containers needed

Round up
Rounding rule for items per container
Rounding rule for items per container
Round down (can't pack partial items)
Formula: Maximum items by weight
Formula: Maximum items by weight
Weight limit ÷ Weight per item
Formula: Area-based packing capacity
Formula: Area-based packing capacity
Container area ÷ Item area
Area calculation vs spatial arrangement
Area calculation vs spatial arrangement
Area = theoretical max; spatial = practical reality
