"Interesting Measurement" Cuboid (2) PPT

Part One: Review Import

Can anyone tell me how to calculate the volume of a cuboid?

The volume of a cuboid is equal to length times width times height

The length of a cuboid is 8 dm, the width is 3.5 dm, and the height is 6 dm. What is the volume of this cuboid?

What is the rate of progression between two adjacent units of length? What about the rate of progression between two adjacent area units?

10,100.

What is the rate of progression between two adjacent volume units? Today we will explore the rate of progression between units of volume.

How to measure the volume of a stone?

Can you find a formula for calculating the volume of this stone? There are many objects like this in life, which we call irregular objects. What other irregular objects like stones are there in life?

Research methods:

Option 1: (Drainage method) Find a rectangular container, put a certain amount of water in it, measure the height of the water surface, sink the stones into the water, and then measure the height of the water surface after it rises. Now calculate how much the water level has risen.

Option 2: (Overflow method) Place the stone into a container filled with water, pour the overflowing water into a graduated measuring cup, and then directly read the volume of the water, which is the volume of the stone.

When measuring the volume of a stone, if the water does not cover the stone, is the volume of the increased water or the volume of the overflowing water equal to the volume of the stone?

Note when measuring:

(1) The water must cover the rocks;

(2) In order to ensure the accuracy of experimental results during the experiment, in addition to accurate calculations, we should also note that we can do several more experiments to find the average of the experimental data.

Interesting measurement PPT, part 3: application exercises

1. What is the volume of this stone?

72mL-55mL=17mL=17 (cubic centimeters)

Answer: The volume of this stone is 17 cubic centimeters.

2. A rectangular container has a bottom length of 2dm and a width of 1.5dm. When a potato is placed, the water level rises by 0.2dm. What is the volume of the potato?

2x1.5x0.2=0.6 (cubic decimeter)

Answer: The volume of this potato is 0.6 cubic decimeters.
