How many boxes for 10x12

Hello Jones and thanks for your question. To estimate the amount of square footage of your room, you would multiply the length times the width (10' x 12'), which would equal the total square feet at 120 and add 10% for cutting waste with a total of 130 sq ft, then dividing by 23.21 sq ft per carton, totaling 5.6 cartons. Hope this helps answer your question. Thanks again for choosing Style Selections Jamestown Hickory Luxury Vinyl Plank.
