To calculate the amount of concrete needed for a 28 by 30 slab, first determine the slab's thickness. For example, if the slab is 4 inches thick (0.33 feet), the volume in cubic feet is 28 ft × 30 ft × 0.33 ft = 277.2 cubic feet. Since there are 27 cubic feet in a cubic yard, you would need approximately 10.3 cubic yards of concrete for the slab. Always consider ordering a little extra to account for spillage and variations in thickness.

How much concrete 30'x40'?
To calculate the amount of concrete needed for a 30'x40' slab, you first need to determine the thickness of the slab. For example, if the slab is 4 inches thick, convert the dimensions to feet (30' x 40' x 0.33' for 4 inches). Then, multiply the length, width, and thickness: 30 x 40 x 0.33 = 396 cubic feet. To convert cubic feet to cubic yards, divide by 27, resulting in approximately 14.67 cubic yards of concrete needed.
How many yards of concrete in a 20ft by 30 ft slab 5 inches thick?
9.3 cubic yards of cement is required for this slab.
How many yards of concrete needed for 24' X 30' X 6 slab?
To calculate the amount of concrete needed for a slab, you can use the formula: volume = length × width × depth. For a 24' x 30' slab with a depth of 6 inches (0.5 feet), the volume is 24 × 30 × 0.5 = 360 cubic feet. Since there are 27 cubic feet in a cubic yard, you would divide 360 by 27, resulting in approximately 13.33 cubic yards of concrete needed for the slab.
How many yards of concrete in a 30 x 40 slab?
To calculate the number of yards of concrete needed for a 30 x 40 slab, first determine the volume in cubic feet. The volume is calculated as length × width × thickness. Assuming a standard thickness of 4 inches (1/3 feet), the volume is 30 × 40 × (1/3) = 400 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 400 by 27, resulting in approximately 14.81 cubic yards of concrete needed for the slab.
How much does a 10' x 30' x 4 slab of concrete weigh?

What is m 30 concrete?
It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
How many yards of concrete needed for 24' X 30' X 6 slab?
To calculate the amount of concrete needed for a slab, you can use the formula: volume = length × width × depth. For a 24' x 30' slab with a depth of 6 inches (0.5 feet), the volume is 24 × 30 × 0.5 = 360 cubic feet.

How much concrete needed for 12x30 slab?
To calculate the amount of concrete needed for a 12x30 slab, you first determine the area by multiplying the length (30 feet) by the width (12 feet), which equals 360 square feet. If the slab is to be 4 inches thick, convert the thickness to feet (4 inches = 1/3 feet) and then calculate the volume: 360 square feet x 1/3 feet = 120 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 120 by 27 to find that approximately 4.44 cubic yards of concrete is needed.
What is C30 grade of concrete?
The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C30 means that the concrete will have a compresion resistance (withstanding a compression) of 30 N/mm2 per square millimetre in 28 days.
How many yards of concrete will a 20 by 30 slab need?
To calculate the amount of concrete needed for a 20 by 30 slab, first determine the area in square feet: 20 feet × 30 feet = 600 square feet. If the slab is, for example, 4 inches thick, convert the thickness to feet (4 inches ÷ 12 inches/foot = 0.33 feet). The volume in cubic feet is then 600 square feet × 0.33 feet = 198 cubic feet. Finally, convert cubic feet to cubic yards by dividing by 27 (since there are 27 cubic feet in a cubic yard): 198 ÷ 27 ≈ 7.33 cubic yards of concrete needed.
How much concrete do you need for a 62ft x 30ft 5 in thick?
To calculate the amount of concrete needed, first convert all measurements to feet. The volume of concrete required can be found using the formula for volume: length × width × height. For a slab that is 62 feet long, 30 feet wide, and 5 inches thick (which is 5/12 feet), the volume is 62 × 30 × (5/12) = 155 cubic feet. Therefore, you will need approximately 155 cubic feet of concrete.
How many yards of concrete it will take to pour a concrete slab that is 30 ft x 10 ft x 4 inches thick?
3.70 yards and you will order 4 yards to have enough. (30 x 10 x 1/3) = 100 cubic feet Divided by 27 = 3.704 cubic yards
