Question 1196753
.


Surely, you can solve the problem, as @ewattr did it, by computing the starting volume, the ending volume

It can be done in one line and in one arithmetic operation, by multiplying the area by the water rise value.


So, this problem teaches you to make your calculations and to organize your solution in a rational form.


It is the major goal of this assignment.
