A 5L measuring cup and a 6L measuring cup, there is no scale, how can you measure 3L of water, how t

Suppose it's measured water:

1.First fill the 6L cup with water, and then pour the water in the 6L cup to the 5L cup, at this time, the 5L cup of water is full of 5L water, and the 6L cup is left with 1L of water;

2.Empty the 5L cup and put the 1L water of the 6L cup into the 5L cup, at this time the 5L cup has 1L of water, and the 6L cup is empty;

3.Fill the 6L cup with water, and then pour it into the 5L cup, just when the 5L cup is poured (the original 1L + 6L cup is poured 4L = 5L), there is still 2L water in the 6L cup (6-4);

4.Empty the water in the 5L cup and pour the 2L water in the 6L cup to the 5L cup, at this time there is 2L water in the 5L cup and the 6L cup is empty;

5.Fill the 6L cup with water, and then pour it into the 5L cup, just when the 5L cup is filled (the 5L cup originally has 2L + 6L cup poured 3L = 5L is just full), the remaining water in the 6L cup is 3L.

I don't know if you can read it.

1. Use the balance to measure the weight of the metal block p1; 2. Fill the glass with water and measure the weight P2 with a balance; 3. Take out the glass filled with water and gently add the metal block to let the excess water overflow. Then measure with a balance.

Measure 6 liters of water first, pour it into a 5-liter measuring cup, pour 1 liter of water into a 5-liter measuring cup, pour this 1 liter into a 5-liter measuring cup, repeat twice, and there will be 3 liters of water left in the 6-liter measuring cup!

Eye-viewing, hehe, isn't it half of 6L?

Fill a 5-litre cup with water and pour it into a 3-litre cup, then fill the rest of the water with another fill, and repeat this until the sum of the remaining water is 4 litres.

Pour the water from the 5L cup into the 3L cup, there is still 2L of water in the 5L cup, pour the water from the 3L cup, pour the 2L water from the 5L cup into the 3L empty cup, and then pour the cup filled with 5L water into the 3L cup with 2L water, then the water in the 5L cup is 4L.

Unit Conversion. 1l = 1000ml 1000ml = 1000 cubic centimeters = 1 cubic decimeter 1 ml = 1 sissi (cc).

1 ml of liquid water = 1 cubic centimeter of liquid water.

1 ml of liquid water weighs 1 gram at 4 degrees Celsius.

1 ml = 1 cubic centimeter.

Measure 3 liters first, pour into a 5-liter cup, then measure 3 liters, pour into a 5-liter cup, at this time there is 1 liter of water in a 3-liter cup, pour the water in a 5-liter cup, pour 1 liter of water from a 3-liter cup into a 5-liter cup, measure 1 3-liter water, pour 5 liters of water, that is, 4 liters of water.

First fill the 5-liter cup, pour water into the 3-liter cup, then pour the water from the 3-liter cup, then pour the remaining 2 liters from the 5-liter cup into the 3-liter cup, fill the 5-liter cup, and then fill the 3-liter cup with the 5-liter cup to get 4 liters of water.

Pour the water from the 5L cup into the 3L cup, there is still 2L of water in the 5L cup, pour the water from the 3L cup, pour the 2L water from the 5L cup into the 3L empty cup, and then pour the cup filled with 5L water into the 3L cup with 2L water, then the water in the 5L cup is 4L.

Fill up 3L, pour all to 5L, fill up 3L, fill 5L with 3L, so that there is 1L left in 3L, pour 5L of water, pour the remaining 1L of 3L into 5L, then fill up 3L, pour into 5L, and have 4L of water.

Put the 5L cup flat and then pick up the 3L cup and align the rim, then the gap at the bottom of the 5L cup is 5-3 is 2L

Then pour water into a 5L cup that is exactly 2, and pour it twice is 4L.

Fill a 5-liter cup with water and pour it into a 3-liter cup, there will be 2 liters of water left in the 5-liter cup, put the 2-liter water into the container; Measure it again according to the method just now, and the energy will be 4 liters of water.

5-3+5-3=4

1. Fill five liters with three liters and two liters remaining.

2. Repeat the above operations.

3. Four liters in hand
