The length, breadth and thickness of a b...

The length, breadth and thickness of a block are given by l=12 cm , b=6cm and t=2.45 cm. The volume of the block according to the idea of significant figures should be

A

`1xx10^(2)cm^(3)`

B

`2xx10^(2)cm^(3)`

C

`1.763xx10^(2)cm^(3)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
l= 12cm, b= 6cm, t= 2.45 cm
Volume = lbt
`=12xx6xx2.45=176.4`
it must be converted inot least significant figures in l, b and t
`=1.764xx10^(2)`
`=2xx10^(2)cm^(3)`
