The density of a cube is measured by measuring its mass and length of its side. If the maximum errors in the measurements of mass and length are 3% and 2% respectively. Then the maximum error in the measurement of density is :

Options

A. `9%`
B. `19%`
C. `10%`
D. `90%`

Answer

A

Explanation

`d = (M)/(V) = (M)/(L^(3)), (Delta d)/(d) xx 100 = ((Delta M)/(M) + (3Delta L)/(L))100`
