Question

A particular dam contains approximately 1,300,000,000,000 cubic feet of water. For a​ week-long spike​ flood, water was released at a rate of 25,200 cubic feet per second.



a. How much water was released during the​ flood?

b. What percentage of the dam was released during the​ flood?

Answer 1

First find how many seconds are in a week.

(1 week)•(7days/week)•(24 hrs/day)•(60min/hr)•(60sec/min) = 604800sec

a.) water released = (25200ft³/sec)•(604800sec) = 1.524•10¹⁰ft³ = 15240960000ft³

b.) % released = (1.524•10¹⁰ft³)/(1,300,000,000,000ft³)•100% = 1.2%
