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.
The equation for volume is V= (pi)(R^2)xH
For Pi use 3.14
So switch the variables for the numbers that we know
V= (3.14)(3^2)x4
3^2= 9
3.14 x 9= 28.26
28.26x9 = 113.04
113.04 to the nearest tenth would be 113.
