переведём все стороны в дм

6м = 60 дм

25см = 2.5 дм

найдём объем

60×2×2.5=300 дм^3

300×650=195000гр=195кг

There are four seasons in a year. They are spring, autumn, summer and winter. Of course, all seasons are nice and every season has its colour.
Winter lasts for three months: December, January and February. The temperature in winter is low. It is frosty, and it often snows. People can go skating and skiing, play snowballs and make snowmen.
Spring begins in March and ends in May. The Sun is warm, the sky becomes blue. The air is fresh, it is full of birds' songs. The trees and the grass are green. There are a lot of beautiful flowers.
The summer months are June, July and August. In summer it is hot, the sky is clear and blue. The days are long and the nights are short and warm. Summer brings us fruit and vegetables. There are a lot of beautiful flowers. It is a very good season for holidays and vacations. We can go to the sea or to the forest and have a good time there.
After summer autumn comes. September, October and November are autumn months. The weather at the beginning is still fine. It is rather warm in the day-time, but it is already cool at night. The sun is not so warm. In October and November it is already cold. It often rains.
It's rather difficult to say what season is the best one, because every season has its own advantages.
