Final answer:
To find the volume of waterproof air pods, Anderson should submerge them in water in a graduated cylinder. This allows him to measure the volume of water displaced, which is equal to the volume of the air pods themselves.
Step-by-step explanation:
To determine the volume of an irregularly shaped object like waterproof air pods, Anderson should submerge the air pods in water in a graduated cylinder. This method is part of a principle known as Archimedes' principle which states that an object submerged in a fluid is buoyed up by a force equal to the weight of the fluid displaced. It's a practical way to measure the volume of objects that do not have regular geometric shapes.
Addressing the options presented in the question:
- Multiplying the length, width, and height of the airpods won't work because this method is for regular-shaped objects, not irregular ones.
- Dividing the air pods density by its weight does not give volume directly, but rather can be used to calculate volume when the density and mass are known.
- Weighing the airpods on a triple beam balance would give the mass, not the volume.
For other measurements, it's important to choose the appropriate tool:
- The volume of a water balloon can also be measured by water displacement using a graduated cylinder.
- The length of a basketball court can be measured using a measuring tape or laser rangefinder.
- The weight of an apple can be determined using a scale.
- The volume of a milk carton can be calculated by multiplying its length, width, and height if it's a rectangular prism, or by using the water displacement method as well.
