Question

The dimensions of rectangular block measured with an instrument having least count 0.01 cm is 4.0mm × 10.0mm × 10.0mm . The maximum percentage error in the measurement of volume of the block is

A. 0.45%
B. 0.045%
C. 4.5%
D. 0.54%

Answer 1

Answer:

l=4.0±0.01mm

b=10.0±0.01mm

h=10.0±0.01mm

V=lbh

∆V/V=∆l/l+∆b/b+∆h/h

(∆V/V)100=(∆l/l+∆b/b+∆h/h)100

=(0.01/4+0.01/10+0.01/10)100

now solve this and you will get answer
