Aquarium

I have an aquarium that is 100 cm long and 40 cm wide and 40 cm in height. We fill it with water. How much will it weigh?

Correct result:

m =  160 kg

Solution:

$$\begin{gathered} a=100\text{ cm}\to \text{ dm}=100\mathrm{/}10\text{ dm}=10\text{ dm } \\ b=40\text{ cm}\to \text{ dm}=40\mathrm{/}10\text{ dm}=4\text{ dm } \\ c=40\text{ cm}\to \text{ dm}=40\mathrm{/}10\text{ dm}=4\text{ dm } \\ V=a\cdot b\cdot c=10\cdot 4\cdot 4=160{\text{dm}}^3 \\ h=1{\text{kg/dm}}^3 \\ m=h\cdot V=1\cdot 160=160\text{ kg} \end{gathered}$$
