find depth of water
The bottom of an underground rectangular tank has an area of $12$ square
feet and the depth of the tank is $10$ feet. A liquid is pumped into the
empty tank at the constant rate of $30$ cubic feet per minute. After how
many minutes will the depth of the liquid in the tank be $8$ feet?
so first volume of rectangular tank is $12*10=120$ cubic,now if water is
pumped $30$ cubic feet per minute,then it takes $4$ minute to fill
tank,but what about $8$ depth,in this case volume would be $12*8=96$,does
it would be $96/30=3.2$ minute?
