You could try measuring the inside and doing the math.
Measuring in Inches, measure front to back, (Depth). Then side to side,(Width). Then top to bottom, (Height). Multiply these together, Depth x Width x Height. This will give you the volume in cubic inches. Divide the number you get in inches by 1728. This will give the volume in cubic feet.

For 5-foot-tall units: A 32 refrigerator or freezer weighs about 150 pounds and takes up 38 cubic feet. A 32-inch refrigerator or freezer weighs about 200 pounds and takes up 44 cubic feet.

20.3 Cubic feet

I am going to guess that it is going to be around 17 cubic feet since that number is in the model number, at least that is how current models are labeled. Here is a link to a copy of the owners manual if you need it.

Here is another link to a page where I looked up the age of your unit and it will give you an idea where to look that up as well.

I would like to know the capacity of my freezer

It is uaually coded into the model #. Usually in the middle. I can usually eyeball them. another solution is measure the outside dimensions of a refrigerator or freezer you know the size of then compare them. This will give you a rough estimate.
