Hi, I need some help.

What does the metaphor "pie in sky" mean?

”pie in the sky“ describes something that is falsely optimistic; a promise of something good happening in the future that is very unlikely to actually take place.

Explanation:

according to archimedes principle, volume of water displaced = volume of water.

hence volume of rock is = 1.65l or 1650 cm^3

explanation:

well stockyards mean a large yard containing pens and sheds, typically adjacent to a slaughterhouse, in which livestock is kept and sorted. and i'm assuming that by party you   mean a large group of people which does make sense because chicago is a very crowded place much like new york. stockyards tend to take up a lot of room due to needing the area for pens to keep animals in and the fact that stockyards are usually right by slaughterhouse where they process and distribute the product. so its much like a zoo but with some dead animal products close by.
