Question

.   The length (L)of a metal bar was measured as (2.65 ± 0.10) cm, the diameter (d)
as (6.14, 6.16,   6.18, 6.19.) mm and the mass as (38 ± 1.0) g

1.    What is the fractional uncertainty in the length?           
2.    What is the absolute error in the diameter of the bar?                              
3.    What is the volume of the bar?                                                               

iv)    What is the absolute error in the volume of the bar?                           

v)      What is the density of the copper bar?  

vii)   What is the percentage error in the density of the copper?
vi)     What is the absolute error in the density of the copper?
