P=4*АD

AD=DC=BC=AB

a=P/4=20см/4=5см

АС=АО+ОС

АО=ОС

A1A=√A1C²-AC²=√100см²-36см²=√64см²=8см

V=AD*DC*A1A=5см*5см*8см=200см³

- Hi Samantha, have you heard anything about the running race? Are there any results?
- Yes, there is a table with all the participants in the hall. There were 7 runners. It was a really tough race.
- Did Sam win the race yesterday?
- No, he was good, but Mark was better than him.
- Was Mark the first?
- No, he came after Billy, just a few seconds later. So, Billy won the race.
- Really?! What a surprise! What about Eddy? What place did he take?
- He was luckier than Mike. So, he was the sixth.
- Oh, that is not bad for him. He broke his leg two years ago and it was his first running race after the accident.
- Did Adam participate in the running race, too?
- Oh, yes, they were running with Chris toe-to-toe…
- Wow, and who was faster?
- Adam. He came 3 seconds faster than Chris.
