The density of a material in the shape of a cube is determined by measuring three sides of the cube and its mass. If the relative errors in measuring the mass and length are respectively 1.5% and 1 % the maximum error in determining the density is

1.	The density of a material in the shape of a cube is determined by measuring three sides of the cube and its mass. If the relative errors in measuring the mass and length are respectively 1.5% and 1 % the maximum error in determining the density is
Answer» `2.5%` `3.5%` `4.5%` 0.06 Solution :Density of cube `=RHO=("Mass M")/("VOLUME V")` `=(M)/((4)/(3)pir^(3))` `:.` Percentage error in density `=(Delta rho)/(rho)xx100%` `=(DELTAM)/(M)xx100%+3(DELTAR)/(r)xx100%` `=1.5%+3xx1%` `=4.5%`
