Question

Select the correct alternative
One litre is equal to :

• A. $1m^3$
• B. $1c{m}^{-3}$
• C. ${10}^{-3}c{m}^3$
• D. ${10}^{-3}{m}^3$

Answer 1

The correct option is D ${10}^{-3}{m}^3$

The volume of liquids is generally expressed in litres.
$1000c{m}^3$ make 1 litre
$1L=1000c{m}^3$
[𝑆𝑖𝑛𝑐𝑒 $1cm={10}^{-2}m$]
$1L=1000\times ({10}^{-2}m{)}^3$ $\Rightarrow 1L={10}^{-3}{m}^3$

Hence option (iv) is correct.
