Question

Density of a cube is measured by its mass and length of the side. If there is 1 %error in the measurement of mass and 3 %error in
measurement of length, calculate the percentage error in the measurement of density

Answer 1

Answer:

use the formula

i am doing another problem

Density,ρ=

Volume

Mass

=

L

3

M

Thus, maximum error,

ρΔρ

=

M

ΔM

+3

ΔL

=0.04+3×0.03=0.13 or 13%
