Question

A swimming pool is 3 meters deep, 50 meters long, and 25 meters wide. If it takes 0.25 pounds of chlorine for every 15 cubic meters of water to keep the pool clean and healthy, how many pounds of chlorine are needed?

a. 27.2 pounds
b. 35.7 pounds
c. 45.4 pounds
d. 62.5 pounds

Answer 1

D) 62.5 pounds.

Explanation:

The volume of the swimming pool =
`3*50*25 =3750`

`3750/15 = 250` lots of 15

`250*0.25=62.5` pounds of chlorine.

Hope this helps, have a nice day!
