Aquarium height

How high does the water in the aquarium reach if there are 36 liters of water in it? The length of the aquarium is 60 cm, and the width is 4 dm.

Correct answer:

c =  1.5 dm

Step-by-step explanation:

$$\begin{gathered} a=60\text{cm}\to \text{dm}=60:10\text{dm}=6\text{dm} \\ b=4\text{dm} \\ V=36\text{l}\to {\text{dm}}^3=36\cdot 1{\text{dm}}^3=36{\text{dm}}^3 \\ V=abc \\ c=\frac{V}{a\cdot b}=\frac{36}{6\cdot 4}=\frac{3}{2}\text{dm}=1.5\text{dm} \end{gathered}$$
