The density of a cube is measured by measuring its mass and length of its sides. If the maximum errors in the measurement of its mass and length are $4 %$ and $3 %$ , respectively, then, the maximum error in density is

Options:

Answer:

Solution:

$ρ = \frac{M a s s}{L^{3}}$

$% e r r o r i n ρ = % e r r o r i n m a s s + 3 [% e r r o r i n l e n g t h]$

$= 4 % + 3 [3 %] = 13 %$
