Rainwater Tank Volume

What volume must a cylinder-shaped tank have to collect rainwater from the flat roof of a cube-shaped house if the house is 12 m wide and reports 50 mm of rainfall?

Final Answer:

V =  7.2 m³

Step-by-step explanation:

$$\begin{gathered} a=12\text{m} \\ h=50\text{mm}\to \text{m}=50:1000\text{m}=0.05\text{m} \\ V=a\cdot a\cdot h=12\cdot 12\cdot 0.05=7.2{\text{m}}^3 \end{gathered}$$
