# The density of a cube is measured by measuring its mass ad length of its side. If the maximum errors in the measurement of its mass and length are $3\%$ and $2\%$ respectively, the maximum error in the measurement of density would be:

$9\%$

##### SOLUTION
Density   $d = \dfrac{Mass}{Volume}$
Or   $d = \dfrac{m}{a^3}$
Percentage error in density  %$\ d =$ %$m +3\times$ % $a$
$\implies$ %$d = 3+3\times 2 = 9$ %

You're just one step away
