In order to estimate the capacity of the compressor in BTU (British Thermal Units) for your room freezer, you will need to know the values of the following parameters/variables:

Room length / width / height, Holding Temp., Ambient Temp., type of product (meat, beer, etc.), product temp. (when you put it in the freezer), insulation type of walls / ceiling / floor , and room window usage (without windows, with glass windows...). The calculations involved are a little complex and rather boring, but fortunately, there are online BTU calculators that may do the job, like this one:

With this type of calc, you can easily determine compressor's BTU capacity "the easy way". Hope this helps.

You want to calculate Volume of room? Use mathematic formula from geometry - if is your room room CUBE, volume is = A 3

If is your room rectangular prism volume is A B C

BUT V is simple to calculate. You need to know others parameters
For what you need that freezer? For fruit or for meat? Its not seem thing.
