Which of the following shows the most reasonable unit of measure for the quantity being measured?
volume of water in a pool; cups
volume of a refrigerator; cubic foot
area of a tennis court; square miles
height of a bookcase; millimeters
volume of water in a pool; cubic foot
is that the correct answer?
Yes, that is the correct answer. The volume of water in a pool is commonly measured in cubic feet.
The most reasonable unit of measure for each quantity would be as follows:
- Volume of water in a pool: cubic feet
- Volume of a refrigerator: cubic foot
- Area of a tennis court: square feet
- Height of a bookcase: millimeters
To determine the most reasonable unit of measure for a quantity, we need to consider the scale of the object being measured.
For the volume of water in a pool, cups would not be a reasonable unit because cups are typically used for smaller measurements. Instead, a larger unit like gallons or liters would be more appropriate.
For the volume of a refrigerator, cubic foot is a reasonable unit. Refrigerators are large appliances, and cubic foot is commonly used to measure the volume of objects with significant dimensions.
For the area of a tennis court, square miles would not be a reasonable unit. While a tennis court is fairly large, square miles are typically used for larger areas like cities or states. A more suitable unit for measuring the area of a tennis court would be square feet or square meters.
For the height of a bookcase, millimeters would not be a reasonable unit. Millimeters are very small and typically used for fine measurements. A more practical unit for measuring the height of a bookcase would be inches, centimeters, or even feet.
In summary, the most reasonable unit of measure for each quantity would be:
- Volume of water in a pool: gallons or liters
- Volume of a refrigerator: cubic foot
- Area of a tennis court: square feet or square meters
- Height of a bookcase: inches, centimeters, or feet
