Question

the density of a material in the shape of a cube is determined by measuring three sides of the cube and it mass .if the relative error in measuring the mass and length are respectively 1.5% and 1% the maximum error in determing the density​

Answer 1

Answer:

Density ρ=

V

m

=

l

3

m

Maximum percentage error in density

ρ

Δρ

×100=

m

Δm

×100+3

l

Δl

×100

⟹

ρ

Δρ

×100=1.5+3×1=4.5%
