Mathematically, a yard is a measure of length, has only one dimension and thus has no volume which has three dimensions; so no matter how many of them you have you will never get a volume of 15 cu ft.
If you are using "yard" in the slang, builders' way to represent cubic yards, then:
1 yd = 3 ft
1 cu yd = 1 yd x 1 yd x 1 yd
= 3 ft x 3 ft x 3 ft
= 27 cu ft
⇒ 15 cu ft = 15 ÷ 27 cu yd
= 5/9 cu yd
≈ 0.56 cu yd
sq feet to sq yards cu ft to cu yards you need depth added to your sq ft to get cu ft such as 70 sq ft x 4 in deep = 23.33 cu ft =.086 cu yd
2.2222222 cu. yards
It would be helpful to have units of measurement in the equation. However, pouring a slab I'll presume your measurements are feet x feet x inches. The volume of this slab is 55 x 15 x 0.5 (6 inches is 0.5 ft) = 412.5 cubic feet 1 yard of cement (more likely concrete as a cement slab will crumble under load) is equal to 27 cu.ft. So, 412.5 cu.ft. needed / 27 cu. ft. / cu. yd. = 15.2777...cu. yards. you will need to order 15.27777...cu. yards, as a yard isn't sold in this decimal you will need to order 15 1/2 yards of concrete to pour your slab.
2.09 cu yds
Total coverage area 314.16 sq. feet. depth of 2 inches = 1.94 cu yards answer ... around 2 cu yards
797 cu yards = 797 * 33 cu feet = 21519 cu ft.
27 cu. ft. = 1 cu. yd.
There are 46.67 cubic yards in 1260 cubic feet. You can convert cubic feet to cubic yards by dividing the cubic feet by 27, as there are 27 cubic feet in a cubic yard.
sq feet to sq yards cu ft to cu yards you need depth added to your sq ft to get cu ft such as 70 sq ft x 4 in deep = 23.33 cu ft =.086 cu yd
2.2222222 cu. yards
I need one and a haft yards of sand. If the bags hold 2 cu feet how many bags do I need
Volume of pit = 9ft * 30ft * 2ft = 540 cubic ft = 540/27 cu yards = 20 cu yards.
Cubic feet of concrete required = 32 x 3 x 0.25 = 24 cu. ft 1 cu yd = 27 cu ft Answer: 24/27 cu yards = 0.89 cu yards.
14.62 cu yds
26 cubic yards = 702 cubic feet
15745 cu-ft or 583 cu-yd of sand
