To determine the most appropriate metric unit to express the volume of air inside a soccer ball, it's useful to consider the approximate size and typical volume of a soccer ball. Let's go through each of the units provided to determine the best fit:
1. Cubic centimeters (cm³):
- This unit is relatively small and is often used to measure the volume of small objects. Given that a soccer ball is much larger than the tiny objects usually measured in cubic centimeters, this unit is not the best choice for our purpose.
2. Cubic kilometers (km³):
- This unit is used to measure extremely large volumes, such as bodies of water or large geographical features. Since a soccer ball is an everyday object and quite small compared to geographical features, cubic kilometers are impractically large for this context.
3. Cubic meters (m³):
- This unit is suitable for measuring volumes of objects that are roughly the size of furniture, rooms, or similarly sized items. Given that a soccer ball is fairly large but not excessively so, cubic meters would provide a reasonable unit to express its volume without resulting in an excessively large or small numerical value.
4. Cubic millimeters (mm³):
- This unit is very small and typically used for measuring minuscule volumes, like grains of sand or very small droplets of liquid. Given the relatively large size of a soccer ball, using cubic millimeters would again be impractically small and result in a very large numerical value.
Given these considerations, the volume of the air inside a soccer ball is best expressed in cubic meters (m³). While cubic centimeters and cubic millimeters could technically measure the volume, they would provide very large and impractical numerical representations. Cubic meters provide a more appropriate and manageable scale for this context.
