Question
The density of a cubr is measured by measuring its mass and length of this sides. If the maximum error in the measurement of mass and lehgth are 4% and 3% respectively , the maximum error in the measurement of density will be
Options
A.7 %
B.9 %
C.12 %
D.13 %
Solution
Density = 
ρ =
% error in density = % errorin mass + 3 (% error in length) = 4 + 3 (3) = 13%

ρ =

% error in density = % errorin mass + 3 (% error in length) = 4 + 3 (3) = 13%
