You don't. You either A) convert 18 cubic inches into cubic feet, or B) convert 18 square inches into square feet. A... there are 1728 cubic inches in a cubic foot, so 18 cu in would be 0.00104 cu ft. B... there are 144 square inches in a square foot, so 18 square inches would be 0.125 sq ft.
72 inches by 36 inches is the same is 6 feet by 3 feet which is 18 square feet.
144 square feet.
Well, isn't that a happy little question! To find the square footage of a rectangle, you multiply the length by the width. In this case, 18 inches by 24 inches equals 432 square inches. To convert that to square feet, you divide by 144 (since there are 144 square inches in a square foot), giving you 3 square feet. Happy painting!
To convert inches to feet, divide by 12 since there are 12 inches in a foot. So, 18 inches is equal to 1.5 feet and 36 inches is equal to 3 feet. To find the area in square feet, multiply the length by the width, which gives us 1.5 feet x 3 feet = 4.5 square feet. Therefore, there are 4.5 square feet in an area that measures 18 x 36 inches.
