RE: Kharrazi contest 1 [Count Challenge] win 10 SBD 😉
3.7m x 5m x 0.6m=11.1cubics
We need to know how many cubics, a person can dig manually.
If we guess that a person can dig 0.3cubics per hour
A person will need 37 hours of work (11.1/0.3=37)
or
37 persons for one hour of work.
to find out how many workers to complete 1 cubic of axavation, you can see my previous post @nikoleondas ;)
