Ответ:

2250000 кг или 2250 т

Пошаговое объяснение:

Переведем км в м:

3 км = 3000 м.

Найдем площадь дороги:

S = a*b = 6*3000=18000 м²

Посчитаем расход асфальта на всю дорогу:

18000*125=2250000 кг = 2250 т

Long-long ago in the Crimean village there were problems with water. So, the men dug seven wells that started to give some water to the local people.
Once, a German man was chosen as the head of the village. He was a wise man and he offered the people to take water free. So everybody was happy to get as much water as they needed.
That man had seven sons. The youngest, whose name was Fritz was the healthiest and strongest in the family. In his childhood he noticed that when some water was taken from the wells, it splashed on the ground. So he didn’t like that and once said to his father, “When I grow up, I’ll ask the village dwellers to pay for the water from the wells. They splash too much water on the ground”. “On, no!” said his father, “water is the most precious thing in this land. It should be free.”
A few years passed. The old German died. Then his six sons died of some disease one by one, and Fritz was made head of the village. He immediately made his wish come true. He said to the villagers that from that day they should pay for the water from the wells. All the wells were locked and Fritz kept the keys to the wells.
One day the village dwellers decided to rebel against Fritz because he told them they wouldn’t have any water for one day.
An old soldier came to the village. He was tired and thirsty and asked for some pure water. Fritz didn’t let him drink because the soldier had no money to pay for it. The soldier begged Fritz to help him. But it was all in vain. When the soldier was dying, he cursed Fritz.
After his death one of the wells was open but the water disappeared from it. When Fritz’s servant opened the other six wells and found no water there, he told it to his master. Fritz was furious. Thus he was punished for his cruelty.
5. Retell the story as if you are one of the village dwellers. Speak about your attitude to Fritz.
