Interesting measurement PPT, part 2: exploring new knowledge

Knowledge points: Measurement method of volume of irregular objects

(1) What method do you have to measure the volume of a stone? Communicate with peers.

(2) Naughty is measured like this, do you understand? Talk to your companions. (Unit: cm)

15×10×（15－10）

=750(cm3)

(3) The picture below is another method of measuring the volume of stones. Follow the steps shown in the diagram. How can you know the volume of a stone?

(4) What other items in life can be measured by the above method? What should I pay attention to when measuring? Group discussion.

Knowledge refining

When measuring the volume of an irregular object, the volume of the raised portion of the water (or the volume of water that overflows when the glass is full) is equivalent to the volume of the irregular object.
