    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!

    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?

    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.
