## Homework Statement

hi there! I am new to this forum and was just wondering if anyone could help with this question on percentage uncertainty. I am supposed to find the percentage uncertainty in d^3

the info given is

mass attached to the end of a strip= 0.1 (+-0.001)kg

the width of the strip = 12.6 (+- 0.1)mm

the thickness of the strip= 0.66(+- 0.01)mm

## Homework Equations

I am also given the equation for youngs modulus

E= 16pi^2 K^2 M/bd^3

## The Attempt at a Solution

I worked out the percentage uncertainty of the thickness of the strip which was approx. 1.52% but am for completely lost

Thank You!
