Block-shaped 19193

The pressure pump delivers two cubic meters of water to the block-shaped water tank in 1 minute. The tank has a 7 m and a width of 5 meters.


How much water does it draw in 1 hour? How high does the water reach in the tank?

Correct answer:

V =  120 m³
h =  3.4286 m

Step-by-step explanation:

$$\begin{gathered} Q=2{\text{m}}^3\text{/min} \\ t=1\text{h}\to \text{min}=1\cdot 60\text{min}=60\text{min} \\ V=Q\cdot t=2\cdot 60=120{\text{m}}^3 \end{gathered}$$

$$\begin{gathered} a=7\text{m} \\ b=5\text{m} \\ V=abh \\ h=V/(a\cdot b)=120/(7\cdot 5)=3.4286\text{m} \end{gathered}$$
