What is the method used to measure the volume of a potato? Write out two ways to measure

The first method: take a container, put in the potatoes, add water, measure the volume, then take out the potatoes and measure the volume again. Take the volume you just measured and subtract the volume you have measured now, which is the volume of the potato The second method is to use its density * its weight = volume.

1.Take the container with a scale of known volume, 2Then put in the potatoes, 3

Fill it with water again, 4Take out the potatoes, 5Read the remaining water volume, 6

Subtraction is used to get the potato volume. OK 2 Fill a bucket with water and put in the water that overflows from the back of the potato, which is the volume of the potato.

Drainage method, calculation method: density x weight = volume.

Fast and natural** gives you a tip:

**There is no rush. Develop healthy lifestyle habits. Be persistent: Diet and exercise equals success!

1. Don't eat snacks, carbonated drinks, drink less and quit cravings. (Junk food is high in calories and easy to accumulate fat).

2. Get eight hours of sleep every day. (Endocrine adjustment) 3. Eat less at dinner and strive for 5 servings. (The proportion of dinner is very high) 4. Exercise appropriately, insist on running in the morning and walking in the evening.

Sleep 4 hours after eating! 5. If conditions permit, insist on eating vegetables every day, eat less greasy food and eat more fruits. (Whitening effect).

The required work is slowed down: a graduated cylinder (the size can be put into potatoes), water;

Steps: (1) Pour an appropriate amount of water into the graduated cylinder (to submerge the potatoes) and write down the scale (volume of water) at this time;

2) Put the potatoes in the graduated cylinder and write down the number scale (water + volume of potatoes) at this time;

3) The difference obtained by subtracting the first scale of Li Mo from the second scale is the volume of the potato

There was a lesson in the textbook to measure the volume of a potato, so I took a potato from my grandmother's house, prepared the clear cup, and I started to do it.

First I brought a very small potato, and then I brought a transparent cup, and the quilt was in the shape of a cube, and I put a little water in it, and I measured it, and the height of the water was 5 centimeters.

I put another potato in the cup, and the cup was full of water, yes.

In the end, I cooled down again, and the edge length of the square was 6cm. Finally, it can be concluded that the bottom area is 6 6 = 36 square centimeters, and then the slag is equal to, multiplied by 36 equals 142 cubic meters, and finally the volume of potatoes can be obtained is 142 cubic meters.

Scheme 1: Name: Drainage Law.

Ingredients: potatoes, water, measuring cup.

Process: Pour water into the measuring cup, look at the scale, put the potatoes into the measuring cup, then look at the scale, subtract the water scale without potatoes from the scale after putting the potatoes, and finally burn the potato date is the volume of the potato.

Data: 200 ml of water without potatoes; Put 350 ml of potatoes in water, 350 minus 200 equals 150 ml.

Conclusion: The volume of this potato is 150 cubic centimeters of blind rice.

Scheme 2: Name: Overflow Law.

Ingredients: potatoes, water, measuring cups, cups, basins.

Process: Put the cup in the basin, pour water just enough into the cup, then gently put the potatoes into the cup, and pour the overflowing water into the measuring cup to measure, which is the volume of the potatoes.

Data: spilled water 150 ml, potatoes volume 150 cubic centimeters.

Conversion rules peel dismantling:

1 ml is equal to 1 cubic centimeter.

<> "Conjecture: Potatoes of the same size are equal in volume Experimental operation: 1

Prepare some potatoes of the same size and wash them. 2.Use a container of mountain shouts to meet in order to soak these potatoes.

3.Gently place one potato in the soaked liquid, being careful not to let the potatoes soak for too long or completely. 4.

If the liquid is on the top of the potato and does not support the potato, use a pair of scissors or other suitable tools to cut the liquid to just support the potato. 5.Gently dry the surface of the potatoes with a towel and note where the liquid is level.

6.Remove the potatoes from the container and place them on a waterless plate. 7.

Measure the length, width, and height of the potatoes with a ruler or tape measure and calculate their volume. 8.Repeat steps 3-7 above to measure all potatoes.

Results: Soaking potatoes of the same size in the same container, we found that the liquid was in the same position, indicating that the potatoes of the same size were equal in volume. By measuring, we found that the volume of potatoes is indeed equal.

Therefore, I can conclude that potatoes of the same size are equal in volume.

Summary. Potatoes are irregular shapes, and it is difficult to calculate the volume with complete mathematical methods.

Generally, it is necessary to use the methods of physics to calculate. For example, a plaster mold (hollow) of a potato is made by making a plaster statue, and water is poured into the mold to weigh the mass of the water, and the grams of water are the cubic centimeters of the volume of the potato. You can also put the potatoes in a measuring cup filled with water and weigh the spilled water, and the grams of the mass of this water are the cubic centimeters of the volume of the potatoes.

Can you calculate the volume of potatoes.

Hello, I have seen your question and am sorting out the answer, please wait a while Potatoes are irregular shapes, and it is difficult to complete the volume calculation with complete mathematical methods. Generally, it is necessary to use the methods of physics to calculate. For example, a plaster mold (hollow) of a potato is made by making a plaster statue, and water is poured into the mold to weigh the mass of the water, and the grams of water are the cubic centimeters of the volume of the potato.

You can also put the potatoes into a measuring cup full of water, and then weigh the overflowing water, and the grams of the leakage mass of this water are the cubic centimeters of the volume of the potatoes.

The volume of an average potato is 450 cubic centimeters.

1.Fill a graduated container with water to see how much there is, then submerge the potatoes in the water (be sure to submerge them).At this time, when you look at the scale of the water, what rises is the volume of the orange potato.

2.There are many examples of omen more than the application in life: for example, awards, according to the number of awards selected by the participants; admit students, according to the number of men and women, etc.; What to do according to the split (which is also the application).

Drainage materials: potatoes, water, measuring cups.

Process: Pour the water into the measuring cup, look at the scale, put the potatoes into the measuring cup, then look at the scale, subtract the water scale without potatoes from the scale after putting the potatoes, and finally the volume of the potatoes.

Data: 200 ml of water without potatoes; Put 350 ml of water with potatoes, 350-200 = 150 (ml).

Conclusion: The volume of this potato is 150 cubic centimeters.
