Three-fifths 3174

The block-shaped pool is 8.5 m long, 4.3 m wide, and 1.5 m deep. How many hectoliters of water is in it when it is filled to three-fifths of the depth?

Correct answer:

x =  328.95 hl

Step-by-step explanation:

$$\begin{gathered} V=8.5\cdot 4.3\cdot 1.5=54.825{\text{m}}^3 \\ {V}_1=V\cdot \frac{3}{5}=\frac{2193}{40}\cdot \frac{3}{5}=\frac{2193\cdot 3}{40\cdot 5}=\frac{6579}{200}=32.895 \\ x=V_1\to \text{hl}=V_1\cdot 10\text{hl}=32.895\cdot 10\text{hl}=328.95\text{hl}=\frac{6579}{20}\text{hl}=328.95\text{hl} \end{gathered}$$
