You need 1.16tonne.
You need to know the weight of a bag of concrete and then divide 1.16 by that weight and that will give you the answer you need.
16 * 20 = 320 sq ft. at 4" thick concrete will cover 80 sq ft. 320 / 80 = 4 yards.
It depends on how thick you want the concrete.
The answer will depend on how large and area you want the topping for. Without that information, no sensible answer is possible.
A cubic yard of concrete covers an area of 81 square feet when poured at a thickness of 4 inches. This is calculated by dividing the total volume of the cubic yard (27 cubic feet) by the thickness in feet (1/3 foot for 4 inches), resulting in 27 ÷ (1/3) = 81 square feet.
To find the area of a concrete cylinder, you typically calculate the lateral surface area and the area of the circular bases. For a cylinder with a height of 12 inches and a diameter of 6 inches, the radius is 3 inches. The lateral surface area is calculated using the formula (2\pi rh), and the area of the two circular bases is (2\pi r^2). Thus, the total surface area would be the sum of these two areas.
8.25 cubic yards of concrete
16 * 20 = 320 sq ft. at 4" thick concrete will cover 80 sq ft. 320 / 80 = 4 yards.
It depends on how thick you want the concrete.
The recommended footings for a concrete slab are typically made of reinforced concrete and should be at least 6 inches thick and extend below the frost line in your area to prevent shifting or cracking.
The answer will depend on how large and area you want the topping for. Without that information, no sensible answer is possible.
To determine how many cubic feet of concrete are needed, you first need to know the depth of the concrete slab. For example, if the slab is 6 inches thick, you would multiply 360 square feet by the thickness in feet (6 inches = 0.5 feet) to get 180 cubic feet of concrete required.
4800 x .33 / 27 = 58.66 yards
You need several quantities to calculate concrete volume for corrugated metal decking. You need both the flute height in inches, flute width in inches, flute foot in inches, sealant depth or thickness in inches, gap size in inches, and deck length in feet.
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
It depends on the thickness and the density. One ton should be about 15 cubic feet when compacted, so it would cover 30 square feet 6 inches thick or 45 square feet 4 inches thick or 60 square feet 3 inches thick. It would make a driveway four inches thick, 9 feet wide and 5 feet long or a footpath 3 inches thick, three feet wide and 20 feet long.
concrete quantity is the amount of concrete required for the construction of an building but in shuttering area is the protection provided for our security
By the yard ... 4" thick and an area 3' by 3' square.
