Block-shaped 6276

288hl of water was filled into a block-shaped tank with bottom dimensions of 12 m and 6 m and a depth of 2 m. What percentage of the volume of the tank did the water occupy?

Correct answer:

p =  20 %

Step-by-step explanation:

$$\begin{gathered} a=12\text{m} \\ b=6\text{m} \\ c=2\text{m} \\ {V}_1=a\cdot b\cdot c=12\cdot 6\cdot 2=144{\text{m}}^3 \\ {V}_2=288\text{hl}\to {\text{m}}^3=288:10{\text{m}}^3=28.8{\text{m}}^3 \\ p=100\cdot \frac{V_2}{V_1}=100\cdot \frac{\frac{144}{5}}{144}=20\% \end{gathered}$$
