From the story of Edison's clever calculation of the volume of the light bulb, I learned that no matter what you do, you must use your brains and ingenuity to solve the problem in the right way, and you can't solve the problem by staying the same. In my future studies and life, I will learn to be ingenious and not copied.

After measuring the empty bulb capacity, it is possible to calculate how much pressure the bulb is subjected to due to the pressure difference between the inside and outside after the bulb is vacuumed, and thus determine how much strength the bulb needs.

Fourth, there are many professional forums and knowledge platforms on the Internet, and there are also a lot of information on them, and I always go to the forum to seek solutions to professional problems.
Fifth, ask your questions more carefully and clearly! It's easier for people to understand what it means!
Thanks for taking my suggestion! !

Fill the bulb with water, pour out the water, and measure the volume of water with a graduated cylinder, which is the capacity of the bulb.
The idea of transformation is used here, where the volume of the bulb is converted into the volume of water in the bulb.

All I know is that he measured it with water.

Edison cleverly calculated the volume of the bulb.
One day, the inventor Thomas Edison gave a light bulb to his assistant, Upton, a mathematics graduate at Princeton University, and asked him to calculate the volume of a glass light bulb. When Edison saw that he was sweating profusely, he said to him, "My God."
You should use this method to calculate! He filled the bulb with water and handed it to Upton and said, "Pour this water into the measuring cup and see its volume, which is the volume of the bulb."
When youngsters learn knowledge, they should combine book knowledge with practice, so that they can learn it lively, remember it, and apply it more easily.

Eddie's approach is skillful [he appropriately transforms the quantitative relationship in the problem, or transforms one problem into another, so that the difficult can often be easily solved and solved smoothly. This method is called the transformation method

You're talking about Edison's water consumption, the volume of light bulbs, right? Edison replaced the light bulb with water, indirectly but simply and accurately measured the volume of the light bulb. Seek adoption.

The shape of the bulb is irregular, and it is difficult to calculate the volume directly.
But if the bulb is filled with water, the volume of the bulb is the volume of the bulb, and the water poured into the measuring cup is very easy to measure.

First measure the diameter of the bottom surface of the bottle with a scale and a triangle, thereby calculate the area of the bottom surface of the bottle S, and then inject about half a bottle of water into the bottle, as shown in Figure 1-4, first the bottle opening is erected upward, the water depth in the bottle is measured with a scale ruler, and then the bottle mouth is tightly closed, the bottle mouth is erected downward, and the height of the air column in the bottle is measured with a scale ruler, then the volume of this bottle is
The calculation method is to divide the total floor area on the site by the planned area, and finally the plot ratio can be calculated. The plot ratio of the house is very suitable in between, and it can also make the living effect of the house better.
