Packaging Efficiency: Significance & Calculation of the Maximum Volume of a Rectangular Box
Packaging Efficiency • What is it? • An efficient, cost-effective way to package products • Why is it important to us? • Goods are individually wrapped or put into containers before they are sold to customers • Even before that, the goods are packaged in large numbers to be shipped to shops • With internet shopping, the goods must be delivered safely to the customers. • Packaging affects us frequently.
Most Efficient Box - Overview • Mathematical Concepts Used • Volume of a Rectangular Prism • y = length * width * height • Polynomial Functions • Expanding/Factoring • Domain/Range • Derivatives • Power Rule • Critical Point (local extrema)

Calculations – Volume Function 2. 4. 1. 3.
Domain & Range – Volume Function • Actual • Domain: • Range: • Unrealistic – negative/large values • Realistic • Domain: (0, 10.45) • Dependent on the limited surface area • Range: (0, 422.11] • Dependent on the domain
Graph of Volume Function Different Width on the Volume of the Box volume (in cm³) width (in cm)
Calculations - Finding Ideal Dimensions (Max Volume) 3. 1. 2. 4.
Ideal Dimensions (Max Volume) Different Width on the Volume of the Box volume (in cm³) width (in cm)
Analysis – Percent Difference 2. 1. Actual Volume:
Summary of Example • Actual Volume: 417.63cm³ • Maximum Volume: 422.11cm³ • Percent Error: 1.06% • Company did an excellent job in packaging its product efficiently.
Other Forms of Packaging • Rectangular boxes aren’t the only shape that packages come in. • Most common though • Easy to stack neatly in trucks • Cylinders • A = πr²h • Cubes • A = s³
Significance of Packaging Efficiency • Internet Shopping Malls • Goods need to be packaged • All goods are delivered • Efficient packaging reduces costs • Companies/Businesses • Goods need to be packaged • Efficient packaging reduces costs • Environmentally Friendly • Less materials used if packages become smaller • *Study published in 1995 indicated that this is one of the best ways to improve the environment.
