A cubical water tank with edges measuring 10 feet in length is initially full of water. If the tank were then to lose water at a constant rate of 10 cubic feet per second, in how many seconds would the tank be full?

Answer :

Manetho

Answer:

100 secs

Explanation:

edge of the cubical tank = 10 feet

volume of the cube is = edge^3

therefore volume = 10^3= 1000 cubic feet

discharge from the pipe Q= 10 cubic feet per second

time taken to fill the tank t= V/Q = 1000/10= 100 secs
