Water lake

The length of the lake water is 8 meters, width 7 meters, and depth 120 centimeters. How many liters of water can fit into the water lake?

Correct answer:

V =  67200 l

Step-by-step explanation:

$$\begin{gathered} a=8\text{m}\to \text{dm}=8\cdot 10\text{dm}=80\text{dm} \\ b=7\text{m}\to \text{dm}=7\cdot 10\text{dm}=70\text{dm} \\ c=120\text{cm}\to \text{dm}=120:10\text{dm}=12\text{dm} \\ 1d{m}^3=1liter \\ V=a\cdot b\cdot c=80\cdot 70\cdot 12=67200\text{l} \end{gathered}$$
