Question

The length l , breadth b and thickness t of a block are measured with the help of a metre scale. Given l = 15.12 ± 0.01 cm , b = 10.15 ± 0.01 cm , t = 5.28 ± 0.01 cm . The percentage error in volume is-

TestHub · Accepted Answer

∆ l l × 100 = 0.01 15.12 × 100 = 0.07 , ∆ b b × 100 = 0.01 10.15 × 100 = 0.1 , ∆ t t × 100 = 0.01 5.28 × 100 = 0.2 Required percentage = 0.066 + 0.098 + 0.189 = 0.35 %
