Aquarium water height

The bottom of the aquarium measures 30 cm and 50 cm. To what height will the aquarium be filled if 60 liters of water are poured into it?

Final Answer:

c =  40 cm

Step-by-step explanation:

$$\begin{gathered} a=30\text{cm} \\ b=50\text{cm} \\ V=60\text{l}\to {\text{cm}}^3=60\cdot 1000{\text{cm}}^3=60000{\text{cm}}^3 \\ S=a\cdot b=30\cdot 50=1500{\text{cm}}^2 \\ V=S\cdot c \\ c=V/S=60000/1500=40\text{cm} \end{gathered}$$
