# Rain

Garden shape of a rectangle measuring 15 m and 20 m rained water up to 3 mm. How many liters of water rained on the garden?

Result

V =  900 l

#### Solution:

$a=15 \ \text{m} \ \\ b=20 \ \text{m} \ \\ c=3 \ mm \rightarrow m=3 / 1000 \ m=0.003 \ m \ \\ \ \\ V_{1}=a \cdot \ b \cdot \ c=15 \cdot \ 20 \cdot \ 0.003=\dfrac{ 9 }{ 10 }=0.9 \ \text{m}^3 \ \\ V=V_{1} \rightarrow l=V_{1} \cdot \ 1000 \ l=0.9 \cdot \ 1000 \ l=900 \ l=900 \ \text{l}$
