Pool Height Volume

What height in meters is my grandfather's pool if it can hold 7350 liters of water, and the lower dimensions of the pool are 2.1 and 2.5 meters?

Final Answer:

h =  1.4 m

Step-by-step explanation:

$$\begin{gathered} V=7350\text{l}\to {\text{m}}^3=7350:1000{\text{m}}^3=7.35{\text{m}}^3 \\ a=2.1\text{m} \\ b=2.5\text{m} \\ S=a\cdot b=2.1\cdot 2.5=\frac{21}{4}=5.25{\text{m}}^2 \\ h=V/S=7.35/5.25=1.4\text{m} \end{gathered}$$
