In the meter reading example, what unit is used for the measurements?

• A. Gallons
• B. Cubic feet
• C. Cubic meters
• D. Liters

Answer: (D)

Meter readings in this example use a metric unit for liquid volume. Liters are chosen because they fit the metric system and keep readings at a convenient scale for typical household or small-scale usage. The other options—gallons and cubic feet are customary units common in the U.S., while cubic meters is a metric unit used for larger volumes; the example’s numbers align with liters to reflect the metric approach.
