<> 9.2 How High? 
In this activity you will learn something about how to determine the volume (how much liquid) there is in the rectangular Tank.
  1. Go to http://nlvm.usu.edu/en/nav/frames_asid_275_g_4_t_4.html (You will see this applet.)

    2.   The container on the left will be partially filled with a liquid.

    3.    How high will liquid go when it is poured from the container on the left to the one on the right?

    4.    Drag the arrow next to the container on the right to the level you think the liquid will reach when it is poured from the container on the left.

    5.    Click Pour.

    6.    The liquid will be poured. Compare the height of the liquid to your guess to see how close you were. 

    7.    Your goal is to figure out where you should place your arrow so that you can always predict accurately where the level of the water will be after you click on Pour. Click New Problem to start a new problem.

8. Describe how you know where to put the arrow.

9. If the height of the liquid is at 6 and the base is 3 by 4, what will the height of the same amount of water be if the base were 2 by 6 instead?
Why?
