Answer:

10cm

Step-by-step explanation:

From the question, we're told that the aquarium is rectangular and the volume of a rectangular figure is can be found by using the below formula;

$V=l\ast w\ast h$

where V = volume = 2400 cm^3

l = length = 20cm

w = width = 12cm

h = height = unknown

Let's go ahead and subsitute the given values into our equation and solve for h;

$\begin{gathered} 2400=20\ast12\ast h \\ 2400=240h \\ (2400)/(240)=(240h)/(240) \\ 10=h \\ \therefore h=10\operatorname{cm} \end{gathered}$

So the height is 10cm
