⇒-- это означает СЛЕДУЕТ

Пошаговое объяснение:

Нижняя сторона= 5*3=15см

верхняя сторона =15, т.к. верхняя и нижняя равны

боковая сторона 3*9=27см

первая боковая= второй боковой

передняя сторона=задней стороне⇒ (5*9)*2=90см

СУММА ВСЕХ СТОРОН=15+15+27+27+90=174см

_____________

Since seven o’clock in the morning, the Madisons had been up and busy around. It was no simple matter to prepare a feast from soup to nuts. Still, Mrs Madison would not change places for anything or anybody. She enjoyed days such as this when all the family- aunts, uncles, cousins, grandparents- came for a visit, each bringing a contribution to the overall festivities. The Madisons, themselves, supplied the turkey. One more Thanksgiving Day. This was a sentimental holiday. It was a suitable time for cozy family reunions. Aside from the origins of the day, extending back to the time of the original settlers, the occasion also reminded the Madisons of the fact that they had to be thankful for living in a country such as the United States. Mr Madison, in particular, always thought of Franklin Delano Roosevelt’s inspiring message:”Let us be thankful that in America we sit down, on this day, to carve up a turkey and not a map”.

I think that the worst place to live would be in a big city. I think that, especially for a family, the only reasonable way to live is to get food locally within a small community that is working together.
There is also such a contrast between cities and smaller towns and villages.One of the reasons we moved from a small with 150,000 people to a smaller town of 10,000 was that the scale and complexity of the place seems so much more manageable.
