Question

(2 класс )помогите решить задачу! В 1ом ведре 12л. Воды,а во 2ом- на 4л. Меньше,чем в первом.Объём воды в двух вёдрах вместе на 20л. меньше,чем в бочке. Чему равна вместимость бочки?

Answer 1

Решение:
1) 12-4= 8 (л) во втором ведре
2) 12+8= 20 (л) объём воды в двух вёдрах
3) 20+20= 40(л) вместительность в бочке

Answer 2

1 12-4=8(л) во второй бочке 
2 12+8=20 (л) в двух вёдрах 
3 20+20=40(л) вместимость бочки

Answer 3

Problem Analysis

To solve this problem, we need to find the capacity of the barrel given the information about the two buckets. Let's break down the information provided:

- The first bucket contains 12 liters of water. - The second bucket contains 4 liters less than the first bucket. - The combined volume of water in the two buckets is 20 liters less than the volume of the barrel.

Solution

Let's assume the capacity of the second bucket is x liters. According to the given information, the first bucket contains 12 liters of water, and the second bucket contains 4 liters less than the first bucket. Therefore, the second bucket contains (12 - 4) liters of water, which is equal to (12 - 4) = 8 liters.

The combined volume of water in the two buckets is 20 liters less than the volume of the barrel. Mathematically, we can represent this as:

(12 + 8) = (x + 20)

Simplifying the equation, we have:

20 = x + 20 - 12 - 8

20 = x

Therefore, the capacity of the barrel is 20 liters.

Conclusion

The capacity of the barrel is 20 liters.
