you multiply 12 x 40 x .333 and then divide it by 27 which will give you 5.92 or 6 yards of concrete
40 yards.
Volume = 11.85 Cubic Yards.
40" x 40" x 3" requires 0.1 cubic yards of cement. If you mean 40 x 40 feet, you will need 14.81 cubic yards of cement.
40 x 40 x 1/2 = 800 cubic feet. Divide 800 by 27 (27 cubic feet per yard) = approximately 29.6 yards.. round that up to 30 cubic yards of concrete.
To calculate how many square yards (SY) of concrete one cubic yard (CY) will cover, first determine the volume of the sidewalk. The sidewalk dimensions are 40 feet wide and 4 inches deep. Converting these measurements, we find that 40 feet equals 13.33 yards, and 4 inches equals approximately 0.11 yards. The volume of the sidewalk is 13.33 yards * 0.11 yards = 1.47 cubic yards. Therefore, 1 cubic yard of concrete will cover approximately 0.68 square yards (1 CY / 1.47 CY).

A 40'x40'x6" slab requires 29.63 cubic yards of cement.
40" x 40" x 3" requires 0.1 cubic yards of cement. If you mean 40 x 40 feet, you will need 14.81 cubic yards of cement.
40 x 40 x 1/2 = 800 cubic feet. Divide 800 by 27 (27 cubic feet per yard) = approximately 29.6 yards.. round that up to 30 cubic yards of concrete.

1 and 1/10 yards. Because there are 12 inches in a foot, and 3 feet in a yardAnswer: 40 " = 1.11111 yds.
24 x 40 x 12in = 24ft x 40ft x 1ft = Volume = 24 * 40 * 1 = 960ft³ = 9.865yd³
To calculate the volume of concrete needed, first convert the dimensions to feet: 40 feet by 40 feet at a thickness of 4 inches (which is 1/3 of a foot). The volume in cubic feet is calculated as 40 ft x 40 ft x (1/3 ft) = 533.33 cubic feet. Since there are 27 cubic feet in a cubic yard, divide by 27 to convert to yards: 533.33 ÷ 27 ≈ 19.7 cubic yards. You would need approximately 19.7 yards of concrete.
40 / 27 = 1.481 yards x $100 = $148.00 + tax. Unfortunately you will have a hard time getting a concrete company to deliver less than 5 yards.
40 yards = 120 feet
