Measuring Mass and Volume: Measuring Volume of Solids

The video tutorial explains how to measure the volume of both regularly and irregularly shaped objects. For regular objects, a metric ruler is used to measure dimensions and calculate volume. For irregular objects, the water displacement method is employed. This involves submerging the object in a graduated cylinder filled with water and measuring the change in water level to determine the object's volume. The tutorial provides a step-by-step guide to using this method, concluding with an example calculation of a rock's volume.

What tool is commonly used to measure the volume of regularly shaped objects?

• A balance scale

• A thermometer

• A metric ruler

• A graduated cylinder

Why is it impractical to use a ruler for measuring the volume of irregularly shaped objects?

• Because they have uneven surfaces

• Because they are too small

• Because they are transparent

• Because they are too heavy

What is the first step in the water displacement method?

• Place the object in the cylinder

• Measure the object's dimensions

• Subtract the initial water level from the final water level

• Fill the graduated cylinder with water to a known level

How do you calculate the volume of an object using the water displacement method?

• Multiply the object's dimensions

• Divide the final water level by the initial water level

• Add the initial and final water levels

• Subtract the initial water level from the final water level

What is the volume of a rock if the water level rises from 40 ml to 51 ml after submerging the rock?

• 11 ml

• 15 ml

• 9 ml

• 13 ml
