Cube

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

Correct result:

x =  0.407 kg

Solution:

m=11 kg k=1/33=1270.037  x=m k=11 0.037=1127=0.407 kgm=11 \ \text{kg} \ \\ k=1/3^3=\dfrac{ 1 }{ 27 } \doteq 0.037 \ \\ \ \\ x=m \cdot \ k=11 \cdot \ 0.037=\dfrac{ 11 }{ 27 }=0.407 \ \text{kg}
