216 square feet. Length x width = square feet.
To calculate the square footage of a space that is 18 feet by 40 feet, you multiply the two dimensions together. So, 18 feet multiplied by 40 feet equals 720 square feet. Therefore, the area is 720 square feet.
Sq footage = 18*25 = 450 square feet.
432 square feet
(18 + 7/12) ft Times (9 + 2/12) ft = 170 25/72 square feet (approx 170.347 sq.ft)
12 feet x 18 feet = 216 square feet.

AnswerCalculate the square inches of a single piece of tile: 18 x 18 = 324 sq in. Convert this to square feet: (you divide by 144, since there are 12 inches in a foot, and you are measuring both height and length in square footage (12 x 12 = 144)324 / 144 = 2.25 sq ft.Multiply this number by the number of tiles you have: 2.25 x 8 = 18 sq feet.
