Week-log Dam Flood Math

Question

A particular dam contains approximately 1,500,000,000,000 cubic feet of water. For a​ week-long spike​ flood, water was released at a rate of 25000 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

25000 x 60 x60 x24 x7 = 1.512 x 10^10 = 1.512 billion

capacity = 1.5 trillion = 1.5 x 10^13

divide

1.512/1.5 x 10^-3= 1.008 x 10^-3 = .001008

= 0.1008 %

= about one tenth of one percent
