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

Options

A. `1 xx10^2 cm^3`
B. `2xx10^2 cm^3`
C. `1.763 xx10^2 cm^3`
D. None of these

Answer

B

Explanation

Volume `(V) = l xx b xx t`
`implies 12 xx6 xx 2.45 = 176.4 cm^3 = 1.764 xx10^2 cm^3`
`~~ 2 xx10^2 cm^3`
When two numbers multiplied or divided, then result is in least significant figure
