Correct result:

x =  31666.7 kg

Solution:

$$\begin{gathered} m\cdot {\displaystyle \frac{12}{100}}\cdot {\displaystyle \frac{0.72}{100}}=0.912 \\ m\cdot 0.12\cdot 0.0072=0.912 \\ m={\displaystyle \frac{0.912}{0.12\cdot 0.0072}} \\ m=1055.56kg \\ x=30m=30\cdot 1055.56=31666.7\text{ kg}=31.7t \end{gathered}$$
