Homework Statement
The maximum error in the measurement of the mass and length of the side of a cube are 3% and 2% respectively. What is the maximum error in the measurement of density? (The questions has options as:- (a)3% (b)5% (c)6% (d)9% (e)12%
Homework Equations
Density(ρ)= Mass/Volume, Volume(cube)= (Length of cube)^3
The Attempt at a Solution
I have thought of two ways to do this:-
1) Just by adding the percentage errors, I get the answer as 5%.
2)Or by adding them like this:- 3% + 3*2%=9%
Please tell me which one of them is the correct one. If both are wrong, please tell me how to solve this problem.
