The volume of a suitcase with the dimensions of 15 inches x 14 inches x 11 inches is 2310 inches3.
It all depends on the other dimensions of the suitcase and also of the trunk. To illustrate this I am going to use some unlikely dimensions. But they should show that you cannot give a proper answer with only partial information. Suppose the 22" suitcase has a height of 8 inches. Suppose the 9 cubic foot trunk has dimensions 36 feet*6inches*6inches ie a long narrow trunk. Then you will not get even a single suitcase in.
76" wide and 80" long

These are different units. Liters is volume (3 dimensions) Kilo is short for kilogram which is mass. If you are measuring water (which conveniently has a density of 1.0) then 1 liter = 1 kilogram But if you have a liter of mercury then 1 liter = 13.6 kilograms

A liter (of anything) is the same as a cubic decimeter.
24*16*10 = 3840 in^3
There are an infinite variety of dimensions and shapes it could be
Not much is known about the dimensions of a 3 liter soda bottle. However, they are said to be 28 inches tall.
You can't convert that. Square centimeters is a unit of AREA (2 dimensions), liter is a unit of VOLUME (3 dimensions).

usually most carriers allow slightly larger suitcases, however it should be avoided unless the cases are considerably smaller in either of the other dimensions

Each liter is equal to approximately 80 cubic inch so 1.6 * 80= 128 cubic inches
