You are correct, based on measurements given.

Aside:
Litres =3D product of side lengths in decimetres :-)
In practice that's handier than it sounds - use lengths in multiples of
either
10's of cm or
100's of mm  or
0.1 of metres
and the end result is litres.
Not overly valuable here but when you have larger object it saves you
having to decide what power of 10 is needed to adjust by afterwards. As
ever, sanity checking the result against a rough mental calculation is
obligatory.

It may deep end on whether you measure it to the front of the open cavity
or with the door shut, depending how the door works.

19 to 23 is a linear growth of 6% in each dimension or, volumetrically
23/19 =3D~ 20% (Actual by your measurements =3D 19.34l =3D 28.9%.

The commerce commission would very likely have a field day with this one
:-).
