1. The Dimensions of a Penny
* Diameter: A US penny has a diameter of approximately 19.05 mm (0.75 inches).
* Thickness: A penny is about 1.52 mm (0.06 inches) thick.
2. Calculating the Volume of One Penny
* Radius: The radius is half the diameter, so it's about 9.525 mm.
* Volume of a Cylinder: A penny is roughly a cylinder. The volume of a cylinder is calculated as π * (radius)² * height.
* Volume ≈ 3.14159 * (9.525 mm)² * 1.52 mm
* Volume ≈ 433.15 cubic millimeters
3. Volume of 25 Pennies
* Total Volume: Multiply the volume of one penny by 25.
* Total Volume ≈ 433.15 mm³ * 25
* Total Volume ≈ 10,828.75 cubic millimeters
4. Converting to Cubic Centimeters
* Conversion: There are 1000 cubic millimeters in 1 cubic centimeter.
* Total Volume ≈ 10,828.75 mm³ / 1000 mm³/cm³
* Total Volume ≈ 10.83 cubic centimeters
Therefore, the volume of 25 pennies is approximately 10.83 cubic centimeters.
Important Notes:
* This is an approximation because pennies are not perfectly cylindrical.
* The volume can vary slightly due to manufacturing tolerances.
