Answer:
[tex]\large \boxed{\text{4.5 ft}}[/tex]
Step-by-step explanation:
The formula for the volume of a tank is
V = base × height
If we are comparing two tanks with equal bases,
[tex]\begin{array}{rcl}\dfrac{V_{2}}{V_{1}} & = & \dfrac{h_{2}}{h_{1} }\\\\\dfrac{27}{30} & = & \dfrac{h_{2}}{5.0}\\\\0.90 & = & \dfrac{h_{2}}{5.0}\\\\h_{2} & = & \textbf{4.5 ft}\\\end{array}\\\text{The height of the second tank would be $\large \boxed{\textbf{4.5 ft}}$}[/tex]
