The tank

The tank has 1320 liters of water and is shaped like a prism. Its base is a rectangle with sides a = 0.6 m and b = 1.5 m. How high is the water level in the tank?

Correct answer:

h =  1.4667 m

Step-by-step explanation:

$$\begin{gathered} V=1320\text{l}\to {\text{m}}^3=1320:1000{\text{m}}^3=1.32{\text{m}}^3 \\ a=0.6\text{m} \\ b=1.5\text{m} \\ S=a\cdot b=0.6\cdot 1.5=\frac{9}{10}=0.9{\text{m}}^2 \\ V=a\cdot b\cdot h=S\cdot h \\ h=V/S=1.32/0.9=1.4667\text{m} \end{gathered}$$
