For this case we have:
The volume of the aquarium, given by a rectangular prism, is:
[tex]V = l * w * h[/tex]
Where:
If we want to clear the height of the aquarium, we must divide both sides of the volume equation between l * w, so we have:
[tex]\frac{V}{(l*w)}=\frac{l*w*h}{(l*w)}[/tex]
[tex]\frac{V}{(l*w)}=h[/tex]
Thus, the height of the aquarium is given by: [tex]h=\frac{V}{(l*w)}[/tex]
Answer:
[tex]h=\frac{V}{(l*w)}[/tex]
