Final answer:
Choosing the right measuring device and unit depends on the object being measured. Graduated cylinders, balances, and measuring tapes are tools used for various measurements of volume, mass, and length, respectively. The measurement is always presented in the most practical and comprehensible units, such as meters for distance, grams for mass, and liters for volume.
Step-by-step explanation:
Choosing the Correct Measuring Device and Unit
When measuring length, mass, and volume, choosing the appropriate measuring device and unit is crucial for accuracy. For instance, to measure the volume of a water balloon, you would use a graduated cylinder to find its displacement, which is suitable for measuring the volume of irregular objects. To measure the length of a basketball court, a long measuring tape is the best tool as it provides the ability to measure large distances in appropriate units like meters. The weight of an apple is best measured using a balance or a scale, appropriate for small objects where precision is important, and the unit will likely be in grams. Similarly, to measure the volume of a milk carton, you can use a ruler to measure its dimensions and calculate the volume if it's of a regular shape, or use displacement method if it's irregular.
The unit chosen will depend on the size and nature of the object being measured. For smaller or more precise measurements, such as the weight of a peanut or the volume of a raindrop, more refined units like grams for mass, or milliliters for volume are used. For longer distances such as the distance between two towns, kilometers would be the appropriate unit. Each measuring tool and unit is selected to provide the most efficient and understandable measurement for the object in question.
