A jug contains 2L of milk. Calcualte the volume of the milk in `m^(3)`

Answer» Since 1L = `1000 cm ^(3)`
and 1m = 100 cm , which gives
`(1m)/(100 cm) =1 = (1 m^(3))/(1 m) `
TO get `m^(3) ` from the above unit factors , the first unit factor is taken ant it is cubed
`((1m)/(100 cm ))^(3) implies (1 m^(3))/(10^(6) cm^(3))=(1)^(3) =1 `
Now 2 L `= 2xx1000 cm^(3)`
the above is multiplied by the unit factor
`2xx1000 cm^(3) xx(1 m^(3))/(10 ^(6)cm^(3)) =(2 m^(3))/(10^(3)) = 2xx10^(-3) m^(3)`
