that is 333 cubic feet,or 12.3 cubic yards At 100 pounds per cubic foot,that is over 33,000 pounds of gravel
A cubic yard is three feet high, three feet wide and three feet thick.
300 square feet x 1/2 foot = 150 cubic feet1 cubic yard = 27 cubic feet150 cubic feet = (150 / 27) = 5 - 5/9 = 5.555cubic yards (rounded, repeating)
It takes up a cubic kilometer of space.
First you have to figure out the area of a the circle using the (pie x r2 )Formula. 12 feet is your diameter, So the radius or r = 6 Pie = 3.14 r2 =36. (3.14 x 36 = 113.04) Now you have to figure out the volume of the slab. volume = area x depth . Seeing we are working with square footage we have to convert the 3 inches to feet. 12 inches in a foot. Divide 3 BY 12. (3 / 12 = .25 ) Now multiply by the area (113.04 X .25 = 28.26) 28.26 cubic ft. is the volume of the slab. To convert to cubic yards you divide by 27. A cubic yard is 3 feet wide 3 feet long and 3 feet high. So (3 x 3 x 3 = 27). Now take the volume in cubic feet 28.26 divided by 27. (28.26 / 27 = 1.046) You need 1.046 cubic yards of concrete to pour a slab 12 feet in diameter 3 inches thick. This is for an exact 3 inch thick by 12 foot diameter slab. If you order from most ready mix concrete firms they'll probably charge for and send 1.25 cubic yards to make sure you have enough.
1.7572 cubic yards
To calculate the volume of dirt needed to fill the area, you would need to know the depth of the area in yards. If the depth is 3 yards, then you would need 1800 yards of dirt (600 cubic yards ÷ 3 yards). If the depth is 1 yard, then you would need 600 yards of dirt.
It would take 135 cubic feet = 5 cubic yards.
To calculate the volume of the area, multiply the length, width, and height: 120 x 92 x 24 = 331,776 cubic inches. To convert cubic inches to cubic yards (since 1 cubic yard = 46,656 cubic inches), divide 331,776 by 46,656 to get approximately 7.1 cubic yards of dirt needed to fill the area.
Assuming you pour to a thickness of 4", this area requires 4.75 cubic yards.
To convert cubic yards to yards, you need to take the cube root of the volume. In this case, the cube root of 150 cubic yards is approximately 5.10 yards.
4 cubic yards is 108 cubic feet.If you were pouring a concrete sidewalk that was 6" thick and 4 ' wide.it would be 54' long.If you wanted to topdress a lawn with loam, guessing an average coverage of 4".It will cover an area about about 16' x 20'With an average coverage of 2" it will do an area roughly 32' x 32'.
If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
Sorry the first answer was in square yds. Cubic yards would be 0.308639
8.25 cubic yards of concrete
An area 20ft x 34' is 680 square feet. 4 inches is 1/3 of a foot so cubic feet required is 680 x 1/3 = 226.7 cubic feet. There are 3x3x3 = 27 cubic ft in a cubic yard. Therefore cubic yards required = 226.7/27 = 8.4 cubic yards
about 17 yards of concrete (it's sold by the cubic yard)
