Rectangular 4546

Thirty watering cans of 8 liters of water are brought to the rectangular garden measuring 15 m and 10 m. During the rain, 2 mm of water fell on the garden. When was the flowerbed more watered?

Correct answer:

V₁ =  240 l
V₂ =  300 l

Step-by-step explanation:

$V_1=30\cdot 8=240\text{l}$

$$\begin{gathered} a=15\text{m} \\ b=10\text{m} \\ h=2\text{mm} \\ S=a\cdot b=15\cdot 10=150{\text{m}}^2 \\ 1l=m^2\cdot mm \\ {V}_2=S\cdot h=150\cdot 2=300=300\text{l} \\ {V}_2>V_1 \end{gathered}$$
