Measuring Volume of Irregular Solids Using Water Displacement

The video tutorial explains how to measure the volume of irregular solids using water displacement, focusing on objects that float, like a wooden log. It introduces the concept of volume and the need for a sinker to measure floating objects. The tutorial demonstrates the process using a metal cube and a wooden block, showing how to calculate the volume of the wooden block by subtracting the volume of the metal cube from the total displacement. The video concludes by encouraging viewers to try the experiment themselves.

What method is used to measure the volume of an irregular solid?

• Archimedes' principle

• Water displacement method

• Buoyancy method

• Direct measurement

What units are used to measure volume?

• Cubic meters and cubic centimeters

• Pounds and ounces

• Liters and milliliters

• Gallons and quarts

What is the initial water level when the metal cube is placed in the measuring cylinder?

• 1100 milliliters

• 1000 milliliters

• 1060 milliliters

• 1140 milliliters

How much water does the metal cube displace?

• 50 milliliters

• 70 milliliters

• 40 milliliters

• 60 milliliters

What is the new water level when both the metal cube and wooden block are submerged?

• 1200 milliliters

• 1140 milliliters

• 1100 milliliters

• 1060 milliliters

How do you calculate the volume of the wooden block?

• Divide the volume of the metal cube by the total displaced water

• Multiply the volume of the metal cube by the total displaced water

• Add the volume of the metal cube to the total displaced water

• Subtract the volume of the metal cube from the total displaced water

Why is a sinker needed when measuring the volume of an object lighter than water?

• To decrease the water level

• To measure the object's weight

• To ensure the object sinks

• To increase the water level
