1.	If the mass and edge of the cube are (10 ± 0.1)kg and (20 ± 0.5) m, 'the maximum possible percentageerror in density is :(A) 9.5 %(B) 8.5%(C) 5.5%(D) 1.5%.
Answer» ANSWER: EXPLANATION: DENSITY = mass/volume % density = (0.1/10 + 30.5/20)100 = (0.01 + 0.075)*100 = 8.5%

Answer»

ANSWER:

EXPLANATION:

DENSITY = mass/volume

% density = (0.1/10 + 3*0.5/20)*100

= (0.01 + 0.075)*100

= 8.5%
