Yards? 12
12
The formula I use is 15 tons = about 12 yards.
you multiply 12 x 40 x .333 and then divide it by 27 which will give you 5.92 or 6 yards of concrete
This cylinder will require 1.4 cubic yards of concrete (this assumes a length of 12' and a width of 2').
15X15X.33(4/12 there is 4 inches in a foot therefor 4" is .33 of a foot) equals 74.25 cf of concrete divide by 27 (three demensional object for yards) 2.75 Cubic Yards. if you try to order .75 cubic yards of concrete you will be laughed at, just order 3 cubic yards and make a entrance path. good luck.
To calculate the amount of concrete needed for a 12 x 15 slab, first find the area in square feet: 12 x 15 = 180 square feet. Then, convert square feet to cubic yards by multiplying the area by the desired thickness (in feet) and then dividing by 27 (since there are 27 cubic feet in a cubic yard). For a standard 4-inch thick slab, the calculation would be 180 x (4/12) / 27, resulting in approximately 2.67 cubic yards of concrete needed.
151/9 cubic yards for every 12 inches thick
To calculate the volume of concrete needed for a floor measuring 12 feet long, 6 feet wide, and 4 inches thick, first convert the thickness to feet: 4 inches is 1/3 of a foot. The volume in cubic feet is then 12 x 6 x (1/3) = 24 cubic feet. To convert cubic feet to cubic yards, divide by 27 (since there are 27 cubic feet in a cubic yard): 24 / 27 ≈ 0.89 cubic yards. Therefore, approximately 0.89 cubic yards of concrete will be needed.
Just type this into Google,(350 *5/12 cu ft) to cu ydand get the answer of5.40123457 cu yd
1.78 cu. yds.
To calculate the volume of concrete needed, first convert the thickness from inches to feet: 4 inches is 1/3 of a foot. The volume in cubic feet is then calculated as 20 ft x 12 ft x (1/3 ft) = 80 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 80 by 27 to find the volume in cubic yards: 80 / 27 ≈ 2.96 cubic yards. Therefore, approximately 3 cubic yards of concrete would be needed.
12 x 24 x.33 = 95.04 cf /27 = 3.52 cubic yards
