Let ‘x’ be the length of one side of the cube.
Therefore x^3 is the volume of the cube.
Now, Volume(v) = x^3
=> Δv/Δx = 3x^2
=>Δv/v = (3x^2/x^3) Δx
=>Δv/v *100% = 3Δx/x *100%
=> (% error in volume) = 3*(% error in measuring sides of cube)
Given, % error in volume = 2%
Therefore, % error in measuring sides = (2/3)%
