# Thread: The height of the water in a rectangular aquarium

1. ## The height of the water in a rectangular aquarium

Hello! Here is a problem I am having some trouble with:

A rectangular aquarium with height 45 cm, length 22 cm, and width 30 cm contains 24 liters of water. What is the height of the water? (Hint: 1 liter= 1000 cubic centimeters)

any help would be appreciated! I do know the answer but have no clue how to reach it!

2. You truly have had no idea how to solve it?

3. No i really dont..someone help I have a test today )= its on our study guide as an example

4. Well, what's the shape of the water in the tank going to be?

5. rectangle.. so far all I have set up is 24/1 x 1000 cm (cubed)/ 1L after that I am stuck

6. $\displaystyle V = Ah$

Since the water is liquid it will fill up the area, A first before filling up any height. You have correctly worked out the volume of water so V is known.

How do you find the area of a rectangle?

7. length x width

8. Indeed and in this example length and width have been given so you can work out the area

9. ## height of water in aquarium

Hi jinger,
A little more help. the volume of water equals base area * height. Dimensions in cm gives an answer in cubic centimeters equal to milliliters (ml) 1000 ml = 1 liter.
