I'm guessing it's a 6 foot by 8 foot patio (but 6 inches, not feet deep). {Note that typically something like a patio may only use 4 inch depth of concrete}. In the case of 6 inches, it should be specified as 6'x8'x6". A yard of concrete has a volume of 1 cubic yard, which is 3x3x3 = 27 cubic feet.
For the patio depth of 6 inches converts to 0.5 feet, so we have 6 ft x 8 ft x 0.5 ft = 24 ft³. Take 24/27 = 8/9 or 0.8889 cubic yards [0.8889 yards of concrete].
If you pour to a standard 4-inch thickness you will need 5.6 cubic yards.
30 square yards.
331/3 cubic yards for each foot of thickness. 27/9 cubic yards for each inch of thickness.
I assume you mean cubic yards (some of us are really rigorous about our units) 600 ftxft (1/3yards/ft)(1/3yards/ft) = 600 (1/9)yards2 = 66 2/3 yards2 4 inch (1/12 ft/inch) = 1/3 ft 1/3 ft (1/3)yard/ft = 1/9 yards 66.66666666 yards2 x 1/9 yards = 7.41 yards3
1 yard = 3 feet 1 cubic yard = 27 cubic feet 1 inch = 1/12 feet Then: Square feet = (100 x 27)/ ( 2 x 1/12) = 2700 x 6 =16200 sq feet
Thickness? Do you mean cement or concrete - cement is the binder/adhesive in the concrete.
If you pour to a standard 4-inch thickness you will need 5.6 cubic yards.
If you use a standard 4-inch thickness you will need a minimum of 6.17 cubic yards.
16 x 16. Actually if you do the math, you could do a 18 x 18, but you never get 4 yards and you rarely get a form that is a perfect .33 feet.
3 cu.yds
8.25 cubic yards of concrete
39.1116 cubic yards
One yard of concrete will cover approximately 90 square feet at a depth of 3-1/2". At an even 3-1/2", you will need just over 3 yards. This does not allow for any footings, turndowns, or a thicker slab.
50/3 cubic yds of concrete
how may yards of concrete are needed for a floor 24 x 25 feet?
One square yard is nine square feet, so 27 square feet is equivalent to 3 square yards. So 3 yards of concrete will cover 27 square feet.
It is not possible to answer the question without knowing whether the patio is 11 ft x 10 ft or 11 yards *10 yards etc.
