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].
To find out how many yards of concrete you need for your 450 sq ft patio, you would first need to determine the thickness of the concrete you plan to pour. Let's assume a standard 4-inch thickness. One cubic yard of concrete would cover 81 square feet at a 4-inch depth. So for a 450 sq ft patio at 4 inches thick, you would need approximately 5.56 cubic yards of concrete.
To calculate the amount of concrete needed for a 900 square foot area, you first need to determine the thickness of the concrete slab. Once you have the thickness in inches, divide it by 36 to convert to yards. Then divide the total cubic yards by the number of cubic yards in a concrete truck to determine how many truckloads you need.
30 square yards.
At 4 mph, you would cover 88 yards in one minute. In 45 seconds, you would cover 66 yards (88 multiplied by 0.75).
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 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.

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.
