It takes 6 men 3hours to build a wall 100cm high. How many men would it take to build a 180cm wall in 2 hours?
------
# of men is directly related to wall height and indirectly related to time.
---------------
m = k*h/t
----
Solve for "k" using "It takes 6 men 3hours to build a wall 100cm high"::
6 = k*3/100
k = 200
------
Equation:
m = 200*h/t
------
How many men would it take to build a 180cm wall in 2 hours?
m = 200*180/2
m = 18000 (# of men required)

If the problem was stated correctly, then it'd take men, but there's nothing such as a fraction of a person, so rounding off, we get: men.
You can do the check!!
