How many hectoliters of water have rained on a rectangular garden measuring 32m and 45m?

Correct answer:

V =  316.8 hl

Step-by-step explanation:

$$\begin{gathered} c=22\text{mm}\to \text{m}=22:1000\text{m}=0.022\text{m} \\ a=32\text{m} \\ b=45\text{m} \\ {V}_1=a\cdot b\cdot c=32\cdot 45\cdot 0.022=\frac{792}{25}=31.68{\text{m}}^3 \\ V=V_1\to \text{hl}=V_1\cdot 10\text{hl}=31.68\cdot 10\text{hl}=316.8\text{hl}=316.8\text{hl} \end{gathered}$$
