How many pennies can fit in a 5-gallon water jug?

Step 1:

Volume of a Penny: 
The volume of a standard U.S. penny is about 0.36 cubic centimeters (cc).

Step 2:

Volume of a Gallon: 
1 U.S. gallon is approximately 3,785 cubic centimeters (cc).

Step 3:

Volume of a 5-Gallon Jug: 
Volume of a 5-gallon jug = \(5 \times 3,785 \space \text { cc} = 18,925 \space \text { cc} \).

Step 4:

Fitting Pennies: 
Since pennies do not pack perfectly due to their shape, we need to account for packing efficiency. A reasonable packing efficiency for cylindrical objects is about 70%. 
Effective volume for pennies = \(18,925 \space \text { cc} \times 0.70 = 13,247.5 \space \text { cc} \).

Step 5:

Number of Pennies: 
Number of pennies = \(\frac { 13,247.5 \space \text { cc} } { 0.36 \space \text { cc/penny} } \approx 36,798.6\).

Step 6:

Rounding: 
Approximate to the nearest thousand for simplicity: 38,000 pennies.

Supplemental Knowledge:

Calculating the volume and packing efficiency of objects into containers is one practical application of geometry. To solve such an equation takes multiple steps involving determining both container volume and item (in this instance a penny) volume before calculating how many can fit within that volume based on both volume and packing efficiency considerations.

Knowledge in Action:

Volume calculations and packing efficiency have many practical uses in daily life, from organizing your pantry to designing storage solutions in warehouses. Understanding what space there is available and the most efficient use for it are crucial considerations when managing an asset like this one.

Imagine working for a logistics firm charged with optimizing cargo space in shipping containers. By applying principles of geometry and packing efficiency, you could ensure more products can be shipped per trip thus cutting costs while increasing productivity.
