Edison asked his assistant to calculate the volume of a light bulb, Edison was a famous inventor. Once, in the process of his busy work, he asked his assistant to help him measure the volume of a light bulb. However, half a day later, his assistant still failed to complete the task. So he went to his assistant's laboratory and found that his assistant was busy studying the shape of the light bulb and carrying out various complicated calculations, A drawing on the desk: divide the light bulb into various shapes and record all kinds of measured data. "I'm almost finished," the assistant said to Edison with pride, "as long as the last set of data is measured!" Edison looked at his assistant with a smile: "you work hard, but can you find a simple and convenient way? I want to know its volume soon!" Students, can you have a more convenient and simple method? (at least 2 methods) please write down your design process and the instrument you need Pay attention to two ways!

1. Equipment
A basin, a water cup (to fit the whole bulb)
2. Methods
Wipe the basin clean, put the cup in the basin, and then fill the cup with water (the surface of the water will flow out of the cup), then put the bulb into the water and press it down with your fingers. At this time, the water flows out of the cup. When the bulb completely submerges into the water and the surface of the water is just level with the mouth of the cup, take out the bulb and measure the volume of the water discharged, which is the volume of the bulb
Sand, measuring cylinder, light bulb
Measurement scheme:
1. Put the bulb into the measuring cylinder and fill it with sand to get the total volume
2. Take out the light bulb and see the volume of the sand
3. The total volume, minus the volume of sand, is the volume of the light bulb



Edison measured the volume of light bulb


There seems to be a little story
One day, Edison asked him to calculate the volume of a light bulb. This man decided to calculate the humiliation and humiliation of Edison in half an hour. He used all kinds of methods and tools to measure, but he was too busy to calculate. An hour passed Edison came and was surprised to find that he hadn't figured it out
So he picked up the light bulb, filled it with water, and then poured the water into the measuring cylinder. In this way, the volume of the light bulb was calculated. From then on, the talented student's attitude towards Edison changed and became a good helper of Edison
