Body calculation?

Hi everyone, I've tried calculating this but I can't seem to get the right answer because of the decimal point, the unit, etc. Can someone please tell me the answers? I don't want to force anyone here; only volunteers can do it. And I've tried many times, but I don't have the time anymore. I have a math test tomorrow and I'm so tired because I studied all day long, and the weeks before, too, but now I can't get anything done. I would really appreciate it if someone could help me 🙂 very much.
