A sealed rectangular container 6 cm by 12 cm by 15 cm is sitting on its smallest face.
It is filled with water up to 5 cm from the top. How many centimeters from the bottom will the water level reach
if the container is placed on its largest face?
~~~~~~~~~~~~~~~~~~~~~~~~~~ 

6*12*5 = 12*15*x.

Find x, which is the value under the question.

The equation expresses the Volume Conservation Law.

If the rectangular container is "sitting on its smallest face", then it is standing on the 6cm x 12cm face. This means the height of the
container in this case is 15cm. "It is filled with water up to 5 cm from the top" means the height of the water inside is 10cm.
The volume of the water inside is therefore 10cm x 6cm x 12cm = 720 cu.cm.
If the container is now placed on its "largest face", the 12cm x 15cm face, the height of the container is now 6cm.
Let the height of the water inside be h.
==> 10cm x 6cm x 12cm = 720 cu.cm. = 12cm x 15cm x h ==> h = 4cm.
