## Aquarium Problem #1

A 2 foot by 3 foot aquarium is filled with 9 inches of water. A 1 foot metal cube is placed in the corner. How much will the water rise?

Is the ToM hibernation season finally over?

Let’s see – volume of water is 2 * 3 * 0.75 = 4.5 cu ft.

With metal cube in place, area of base is now 5 sq ft.

So height of water is now 4.5 / 5 feet = 10.8 inches.

So rise in water level is 1.8 inches.

I was interested in getting more problems to solve on here, so I figured I would seed the idea with a few quick problems myself.

I did a quick search on the web and found a similar problem. Tweaked it just a little and added some variations (ass you see in probs #2 and #3).

But to your solution, Wiz, you are correct. 1.8 inches would be the answer for this question.
