Oak Lumber flooring Calculation

I am wanting to cover a 120 sqft room. I need to figure out 2 3/4 wide and 1 linear inch would it take to cover the room?
Could you please show the calculation?
John

120 x 12 = 1440 sq. inches

1440 / 2.75 = 523.636 linear inches

add ten percent to the final number and that will be the ammount to order. waste and undesirable boards, trust me there will be a few.

Revised Calculations

I think you might take another look at your calculations. I came up with something different.

1 sq ft = 12 in x 12 in = 144 sq in

So 120 sq ft = 120 x 144 sq in per sq ft = 17,280 sq inches

17,280 sq in / 2.75 in width = 6,284 in length. So you need
6,284 in / 12 in per foot = 524 feet of flooring that is 2 3/4 wide to fill a 120sq ft room.

Adding the 10% margin, you get
1.1 x 524 ft = 576 feet of flooring required for the job.

I think this correct. To give it a sanity check, if your room was 12 ft wide by 10 ft long (120 sq ft), you would need 12 ft x 12 in per ft/2.75 in wide = 144/2.75 = 52.4 strips laid side by side to span the width of the room. Since each one of those strips has to be 10 feet long, you need a total length of 52.4 x 10 = 524 feet of flooring. Add 10% margin and you need 1.1 x 524 = 576 feet required. Same answer as before.

I hope this helps. I was just passing by, trying to get smarter on wood flooring, and I saw the post on calculating footage for a 120 sq ft room. I thought I would throw in my 2 cents worth.

Lets take this one step further

If the boards come in 5' lengths X 6" and are .20 a lineal inch how much would it cost? John

So If each box of tongue and groove flooring covered 17.8 square feet of space and the room was 19' x 12' then you would :

(1) multiply 19'x12' =228 square feet +22 waste and cast offs then
(2) divide 250'/17.8'= 14. Am I right? How many 4'x8' sheets of playwood do I need to cover the area?
I come up with 8 roughly. Did I do that right?

After 8 years, and you haven't got this project done, yet?? Yes 14 boxes of flooring at your current specifications. Plywood comes in 4x8 sheets, or 32 square feet. Divide your room total by 32. You will need 8 sheets of plywood.
