Answer 1

kindly give rating

"Volume = V = b^2 times H therefore delta V/V = 2 delta b/b + delta H/H = 2 times 0.05/2.5 + 0.05/2.3 = 0.06174 Density D = M/V therefore delta D/D = delta M/M + delta V/V = 10/100 + 0.06174 = 0.16174 therefore delta D = 0.16174 times 2.68 = 0.4335 g/cm therefore Density is in the range = 2.68 plusminus 0.4335 therefore Material is ""Aluminium"""
