Pool

The swimming pool is 10 m wide and 8 m long, and 153 cm deep. How many hectoliters of water are in it if the water is 30 cm below its upper edge?

Correct answer:

V =  984 hl

Step-by-step explanation:

$$\begin{gathered} a=10\text{m} \\ b=8\text{m} \\ {c}_1=153-30=123\text{cm} \\ c=c_1\to \text{m}=c_1:100\text{m}=123:100\text{m}=1.23\text{m} \\ {V}_1=a\cdot b\cdot c=10\cdot 8\cdot 1.23=\frac{492}{5}=98.4{\text{m}}^3 \\ V=V_1\to \text{hl}=V_1\cdot 10\text{hl}=98.4\cdot 10\text{hl}=984\text{hl}=984\text{hl} \end{gathered}$$
