The length l , breadth b, and thickness ...

The length l , breadth b, and thickness `t` of a block of wood were measured with the help os a measuring scale. The results with permissible errors ( in cm) are
`l = 15.12 +-0.01, b = 10.15+-0.01` , and `t = 5.28 +- 0.01`.
The percentage error in volume up to proper significant figures is

A

`0.28 %`

B

`0.35%`

C

`0.48%`

D

`0.64%`

Text Solution

Verified by Experts

The correct Answer is:
B
Percentage error in volume is
` ( 0.01)/( 15.12) xx 100 + ( 0.01)/( 10.15) xx 100 + ( 0.01)/( 5.285) xx 100 = 0.35%`
