None, since there can be no conversion. A foot is a measure of length in 1-dimensional space while a cubic yard is a measure of volume in 3-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
300 feet by 100 feet by 10 feet = 300,000 cubic feet
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)
300 feet. There are three feet per yard.
300. Three feet per yard.
Let's convert everything to one unit. So we have 20' x 30' x 6" which when converted to feet (only the 6") results in 20' x 30' x 1/2' = 300 cubic feet One cubic yard is 3' x 3' x 3' = 27 cubic feet Hence 300 cubic feet is 300/27 cubic yards = 11.111
300 cubic feet.
Volume = (base area) x (height) = 300 cubic feet = 111/9 cubic yard.
300 cubic feet = 2,244.156 gallons (rounded)
1 yard = 3 feet so 100 yards = 100*3 = 300 feet. Simple!
3 feet = 1 yard therefore 300 feet = 100 yards
To calculate the volume of concrete needed, first convert the dimensions to feet: a 30x30 area is 30 feet by 30 feet, and 4 inches is 1/3 of a foot. The volume in cubic feet is 30 x 30 x (1/3) = 300 cubic feet. To convert cubic feet to cubic yards, divide by 27 (since there are 27 cubic feet in a cubic yard): 300 ÷ 27 ≈ 11.11 cubic yards. Therefore, you need approximately 11.11 yards of concrete.
22.2 cubic yards.
