Cube

The cube weighs 11 kg. How weight is a cube of the same material if its dimensions are 3-times smaller?

Correct answer:

x =  0.4074 kg

Step-by-step explanation:

$$\begin{gathered} m=11\text{ kg } \\ k=1\mathrm{/}{3}^3={\displaystyle \frac{1}{27}}\doteq 0.037 \\ x=m\cdot k=11\cdot 0.037=0.4074\text{ kg} \end{gathered}$$
