Aquarium

An aquarium is a rectangular cuboid with a square base. It contains 62 litres of water and the base edge is 34 cm long. To what height does the water level rise?

Final Answer:

h =  53.6 cm

Step-by-step explanation:

$$\begin{gathered} V=62\text{l}\to {\text{cm}}^3=62\cdot 1000{\text{cm}}^3=62000{\text{cm}}^3 \\ a=34\text{cm} \\ S=a\cdot a=34\cdot 34=1156{\text{cm}}^2 \\ V=S\cdot h \\ h=V/S=62000/1156=53.6\text{cm} \end{gathered}$$
