What are your thoughts? What have you tried? How far have you gotten? Where are you stuck?

For instance, you first found the area of the base of the tank. Then, using the height, you found the volume of the tank, in cubic centimeters. You noted the rate of flow and the time of flow; you then used this information to find the number of liters used to fill the tank to the indicated height. You noted that the volume of the tank consists of two sub-volumes: the volume of the water and the volume of the rock. You converted the cubic-centimeter volume of the tank into liters, and compared with the liters poured into the tank. And... then what?

Please be complete. Thank you! ;)

SO
VOL of tank = 2000 *18 =36000 cm3
next 36000/1000cm3= 36 lts
rate of flow=10 lts *3 min =30 lts
so 36 lts minus 30 lts= 6lts= 6000 cm3 is volume of stone.
is that right?
