Sagot :

From the volume computed, since each box contains 5000 grams of chlorine powder, it won't be enough for 4 weeks.

How to calculate the volume

The volume of the swimming pool water will be:

= length × width × height.

= 20 × 8 × 1.8

= 288m³

Since 50m³ of water chlorine needs 300gm, therefore, 1m³ will need;

= 300/50 = 6

Therefore, 288m³ will need:

= 288 × 6 = 1728gm

The amount of chlorine powder needed for 4 weeks will be:

= 1728 × 4

= 6912 gm

Since each box contains 5000 grams of chlorine powder, it won't be enough for 4 weeks.
