Understanding Volume

The video tutorial introduces the concept of volume by using a measuring jar. It demonstrates how to measure the volume of various objects, such as a marble and a matchbox, using water displacement and sand. The tutorial also explains the formula for calculating the volume of a cube. Finally, it compares the volumes of a square prism and a triangular prism by filling them with sand and measuring the displaced water.

What is the purpose of using a measuring jar in the video?

• To measure the volume of objects

• To measure the volume of liquids

• To measure the temperature of liquids

• To measure the weight of objects

How is the volume of a marble determined in the video?

• By observing the rise in water level when submerged

• By calculating its surface area

• By measuring its diameter

• By weighing it

What formula is used to calculate the volume of a cube?

• A + A + A

• A x A x A

• A / A / A

• A - A - A

Why does the water level not change when a matchbox is placed in the jar?

• The matchbox is too small

• The matchbox is lighter than water

• The matchbox is already filled with water

• The matchbox is waterproof

How is the volume of the matchbox determined?

• By weighing it

• By filling it with sand and observing the water level change

• By measuring its dimensions

• By filling it with water

Which prism had the larger volume in the comparison?

• Neither had any volume

• The square prism

• Both had the same volume

• The triangular prism
