Accuracy; precision of instruments and errors in measurements

Question

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

Moderate

A

7%
B

9%
C

12%
D

13%

Solution

$ρ = \frac{m}{V} = \frac{m}{l^{3}} = m l^{- 3}$
Maximum % error in p=(% error in m) +3(% error in t)
