Multiply width by length to get the area. The answer would be 360 square feet which is 40 square yards.
one square yard equals nine square feet. So in maths terms you divide (13.5 times 11.5) which equals 155.25 sq yards. by nine and the answer is 17.25 sq yards. but if you covering a floor then you will most likely need eighteen sq yds.
15'x33' (495 square feet) = 55 square yards of floor.
how may yards of concrete are needed for a floor 24 x 25 feet?
1 square foot is 0.111 square yards. The floor area is 9feet x 21feet = 189 square feet. Therefore, the total square yards is: 189 square feet x 0.111 square yards/foot squared = 21 square yards Therefore, there is 21 square yards of floor.
25.33 yards
348 square feet are 38.666667 square yards.
At least 31.77 square yards are needed.
20 square yards are needed
14 square yards (assuming you are purchasing whole square yards)
15' x 17' (255 square feet) = 28.3 square yards.
9' x 9' (81 square feet) = 9 square yards.
