I know, but what is the effect of calling Dp.toPx() inside 
with(){}
?

You can't call it otherwise. You have to be in 
Density
context (
this is Density
) to access this conversion extension function. You could also do 
LocalDensity.current.run { sizeDp.toPx() }

It's because this extension function is defined in 
Density
interface so it has two receivers (contexts). One is 
Density
and one is 
Dp
defined on the function
