Question

How do you convert a volume of 8 deciliters to liters?

Answer 1

`"8 decilitres"` `-=` `0.8*L`

Explanation:

`"1 decilitre"` `-=` `1xx10^-1*L`,

`"8 decilitres"` `-=` `8xx10^-1*L` `=` `0.8*L`.

`"deci"` `-=` `10^-1`.

Note that `1*dm^-3` `=` `(1xx10^-1m)^3` `=` `10^-3*m^3` `=` `1*L`, because there are `10^3L*m^-3`.
