Question

Find the % error in measurement of volume of a block of length 10cm,breadth 20 cm and height 25cm ,if measurment are carried by metre scale.​

Answer 1

solutions .................

Answer 2

Answer:

1.9 %

Explanation:

The least count of a meter scale is 1 mm. Hence absolute error in length, breadth and height  is

| ΔL | =| ΔB | = | ΔH |  = 1mm = 0.1cm

As V = L×B×H

% error in Volume= % error in L+ % error in B+ % error in H

         =$\frac{0.1}{10}$×100 + $\frac{0.1}{20}$×100+$\frac{0.1}{25}$ ×100

        =1.9%
