If I Had A Room That Measured 12*12....how Much Would I Need To Cover The Floor W/hardwood Flooring?

You will need 144 square feet of flooring to cover a 12'x12' foot room.
It is a good idea to have a few extra feet just in case you mis-cut some of the flooring when laying around the cabinetry.
You don't say how long and wide your cabinets are, so I can't give you an exact measurement for the room.
But, you can measure length and width, take the two numbers and times them by each other. Length times width will give you the square footage of the cabinet area. Once you have figured the footage of the cabinets, you can subtract it from the overall size of the room.
To be safe, I recommend that you purchase one extra box of flooring material.
Be sure to follow the manufacturers recommendations on maintaining your new wood flooring. Some are made of different materials such as laminates and bamboo. You don't want to ruin your beautiful new floors by applying the wrong cleaning and polishing compounds to them.
Also, be sure that you check to make sure that you purchase all the same lot numbers on all boxes of material. It will sometimes and most often be a difference in shade and size from lot number to lot number.

If you mean 12X12 feet then it equals to 144 inches. So you need 144 inch hardwood flooring. If you buy blocks of 1 by 1 foot then you would need only 12 blocks to cover your room. Click here to get some information about hardwood flooring.
