Правильный ответ
m =11,93 кг.
ρ = 19300 кг/м^3.
V - ?
Плотность вещества ρ определяется формулой: ρ = m /V, где m - масса вещества, V - объем вещества.
Объем вещества найдем по формуле: V = m /ρ.
V = 11,93 кг / 19300 кг/м^3 = 0,0062 м^3 = 0,62 л.
Ответ: V = 0,0062 м^3.

Вопрос по английскому языку:
Помогите сократить текст пожалуйста!!!
Did you know that TV in Russia is similar to TV in other European countries? We didn’t know what to expect when we read the programme guide. Then we saw Russian versions of lots of familiar shows like Big Brother and Who Wants to be a Millionaire?
Russian TV also has a few soap operas, as in almost every other place in the world, and we even recognised some soaps from the UK!
Russian television has over twenty channels on the air and these are both public and private. One of the most popular channels is Channel One, where you can see Star Factory. This is one of Russia’s most popular reality shows.
We saw lots of adverts for variety shows and comedy shows. These are very popular. Russians really like to laugh and they enjoy watching funny sketches and stand-up comedians especially when they tell jokes about politics. One of these lands of programmes is the popular KVN. It is one of the best programmes to watch if you want to understand Russian humour. Even though we didn’t understand the language it was very funny to watch.
Of course there are also lots of American and European films on television. In fact, with so many different types of programmes we found it hard to choose!
