0.246914 cu. yards (6.666667 cu. ft ) of concrete is needed.
Ah, what a lovely question! To find the area of a 20ft by 20ft square, we simply multiply the length by the width. So, 20ft x 20ft equals 400 square feet. To convert this to square meters, we need to remember that 1 square meter is approximately 10.76 square feet. Therefore, the area of a 20ft by 20ft square is about 37.16 square meters. Isn't that just delightful?
They are the same.
8 inches = 8/12 ft = 2/3 or .66 ft 20ft X 21ft = 420ft2 X .66ft or 2/3ft = 280ft3 (feet cubed )
20ft X 14ft = 280 sq ft /9 = 31.11sq yds X $3.00 = $93.33

5 yds - One yard of concrete will cover approximately 81 square feet 4" deep.
To calculate the amount of concrete needed for a 24ft by 20ft slab that is 4 inches thick, first convert the thickness to feet (4 inches = 1/3 feet). The volume in cubic feet is then 24ft × 20ft × (1/3)ft = 160 cubic feet. To convert cubic feet to cubic yards (since concrete is often sold by the cubic yard), divide by 27: 160 cubic feet ÷ 27 = approximately 5.93 cubic yards. Therefore, you would need about 6 cubic yards of concrete.
That depends on how DEEP you want the concrete !
9.3 cubic yards of cement is required for this slab.
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.

242/12, ie 20ft 2 in
20 feet x 20 ft x .3333 ft = 133.33 cubic feet / 27 cubic feet per yard = 4.94 cubic yards
google it people thats y its there smart ones
106.67 Cubic Yards
20 times 50 divided by three is 333 1/3
For an area that is 20ft by 20ft and you want to add 6 inches of topsoil, you will need 20 cubic yards of topsoil. Topsoil is typically ordered by the cubic yard, so this measurement will ensure that you have enough to cover the entire area with a 6-inch layer.
