Answer:
300 m
Step-by-step explanation:
Volume is the measurement of how much space there is inside of a 3-D object.
For a rectangular prism, which this fish tank is, the formula for its volume given its dimensions is,
[tex]lwh=V[/tex],
where l is the length, w is the width and h is the height of the prism.
The problem has given us the length and width of the tank and its volume--if the tanks hold 36 liters water then the tank can hold 36 liter of space-- and asks for its height.
We can use the volume formula, plug in the known values and rearrange to find the value of h!
[tex](0.3)(0.4)h=36[/tex]
[tex]0.12h=36[/tex]
[tex]h=\dfrac{36}{0.12} =300[/tex]
So, the height of the tank is 300 meters.
