Answer:

  no, it is good for 2 weeks (almost 3)

Step-by-step explanation:

The volume of the pool is ...

  V = LWH

  V = (20 m)(8 m)(1.8 m) = 288 m³

Then the amount of chlorine powder needed for 1 week is ...

  (300 g/(50 m³)) × (288 m³) = 1728 g

A box of 5000 g holds enough chlorine for ...

  (5000 g)/(1728 g/treatment) = 2.89 treatments

A box of chlorine powder is enough for 2 weeks, not 4.
