Swimming pool

The swimming pool is shaped like a block and has dimensions of 70dm, 25m, and 200cm. How many hectoliters of water can fit into the pool?

Correct answer:

V =  3500 hl

Step-by-step explanation:

$$\begin{gathered} a=70\text{dm}\to \text{m}=70:10\text{m}=7\text{m} \\ b=25\text{m} \\ c=200\text{cm}\to \text{m}=200:100\text{m}=2\text{m} \\ {V}_1=a\cdot b\cdot c=7\cdot 25\cdot 2=350{\text{m}}^3 \\ V=V_1\to \text{hl}=V_1\cdot 10\text{hl}=350\cdot 10\text{hl}=3500\text{hl}=3500\text{hl} \end{gathered}$$
