Perhaps you should have paid more attention in your Math Lessons all those years ago... Although why you should want this information is a complete mystery (to me)...
You willl need a tape rule graduated in inches - a piece of paper, a pencil and a simple calculator.
First we discover the number of cubic inches in a cubic foot... 12x12x12 = 1728 (easy)
Now measure your machine (if you don't have it any more this may be difficult) and write down H x W x D in Inches and decimals of an inch i.e 37.5 rather than 37½
Multiply all three together and divide the product of these by 1728 - the final answer is in Cubic Feet.
Quite how you will use this volume information I can't comprehend - unless you're shipping it somewhere and the charges are volume based perhaps.
From what I can gather the answer is about 12.7cu ft. Just what difference will it make if it's say, 14.8cu ft one wonders?
Good luck...
