Hi. I need to convert 14 LY of wallcovering (54" wide) to square feet. Can you please help me? \

I am not sure of the formula... thank you SOOO much!


You need 14 yards of wallcovering that comes in 54 in wide rolls and you want the area in square feet. The mixture of yards, inches and feet causes difficulty so let's convert all the units to feet. There are 3 feet on a yard so 14 yards is 3 × 14 = 42 feet and there are 12 inches in a foot so 54 inches is 54/12 = 4.5 feet. Thus 14 yards by 54 inches is 42 × 4.5 = 189 square feet.
