What is its spring constant?Explanation / Answer
1] Density p = m/volume = m/[xyz] = 0.200/[0.10*0.06*0.01] = 3333.33 kg/m^3
p = m/xyz
ln p = ln m - ln x - ln y - ln z
since errors always add up, dp/p = dx/x +dy/y+dz/z
dp = 3333.333*[0.05/10+0.01/6 +0.001/1] = 25.55 kg/m^3
p+- dp = 3333.33 +- 25.55 kg/m^3
