Rainwater

6 mm of water rained on the garden with an area of 25 acres. How many 12 liter cans of water would we water this garden just as much?

Correct answer:

n =  1250

Step-by-step explanation:

$$\begin{gathered} S=25\text{ a}\to {\text{m}}^2=25\cdot 100{\text{m}}^2=2500{\text{m}}^2 \\ h=6\text{ mm}\to \text{ m}=6\mathrm{/}1000\text{ m}=0.006\text{ m } \\ V=S\cdot h=2500\cdot 0.006=15{\text{m}}^3 \\ {V}_1=V\to \text{ l}=V\cdot 1000\text{ l}=15\cdot 1000\text{ l}=15000\text{ l } \\ {V}_2=12\text{ l } \\ n=V_1\mathrm{/}{V}_2=15000\mathrm{/}12=1250 \end{gathered}$$
