Aquarium 3432

The aquarium has the shape of a block with a length of 0.7 m and a width of 25 cm. It can hold 56 liters of water. How deep is the aquarium?

Correct answer:

h =  32 cm

Step-by-step explanation:

$$\begin{gathered} a=0.7\text{m}\to \text{cm}=0.7\cdot 100\text{cm}=70\text{cm} \\ b=25\text{cm} \\ V=56\text{l}\to {\text{cm}}^3=56\cdot 1000{\text{cm}}^3=56000{\text{cm}}^3 \\ V=a\cdot b\cdot h \\ h=V/(a\cdot b)=56000/(70\cdot 25)=32\text{cm} \end{gathered}$$
