Final answer:
The correct unit to measure the volume of a pool is Gallons, which is the most suitable unit for large capacities of liquid like water in a swimming pool. The correct answer is B) Gallons.
Step-by-step explanation:
When we are referring to the volume of a pool, we need to think about the unit of measurement that would accurately reflect the amount of space within the pool. The correct answer is B) Gallons. Gallons are a unit of capacity in the American system of measurement, and it is the most appropriate unit for large volumes of liquid required for areas like swimming pools.
Pounds refer to weight, inches and Fahrenheit are units to measure length and temperature, respectively. Neither of these is correct when we're trying to figure out how much water a pool can hold.
When Darcy is filling up her swimming pool, she would use gallons to measure the amount of water needed because it's the largest unit for capacity which is suitable for the volume of a pool.
For example, if the pool is large, measuring in smaller units like ounces or cups would be impractical and ineffective for understanding the volume. Gallons allows for a more understandable and usable figure.
When measuring the volume of a pool, the unit used is gallons.
For example, if Darcy is filling up her swimming pool, she would measure the amount of water needed in gallons.
The correct answer is B) Gallons.
