Andrei has a glass tank. First, he wants to put some marbles in it, all of the same volume. Then, he wants to fill the tank with water until it's completely full. The equation shown above describes the volume of water, WW, measured in liters, that Andrei should use when there are nn marbles. What is the volume of the glass tank, in liters?
Hmmmm..... I corrected this post due to guest's input below ! Thanx ! I can tell you that 640 marbles will completely fill the aquarium.
