24 x 40 x 12in = 24ft x 40ft x 1ft = Volume = 24 * 40 * 1 = 960ft³ = 9.865yd³
To calculate the volume of concrete needed for a slab that is 30 feet by 40 feet and 4 inches thick, first convert the thickness to feet: 4 inches is 1/3 foot. The volume in cubic feet is 30 x 40 x (1/3) = 400 cubic feet. To convert cubic feet to cubic yards, divide by 27 (since there are 27 cubic feet in a cubic yard): 400 ÷ 27 ≈ 14.81 cubic yards. If footers are included, you would need to add their volume based on their dimensions to this total.
Yards are for measuring length not volume. Cubic yards required will be as follows: 1 cubic yard = 3 feet x 3 feet x 3 feet = 27 cubic feet Your concrete pad is 30ft x 40ft x 0.3333ft (4 inches assumed) = 400 cubic feet 400 divided by 27 = 14.8148 cubic yards required

12 inches * 40 = 480 inches
First of all divide 2" by 12" to get 0.1666 feet; then multiply 0.1666' x 40' x 40' which equals 266.56 cubic feet; Multiply 266.56 cubic feet x 0.03704 to get 9.8734; Therefore, 2 inches of topsoil from an area 40 feet by 40 feet = 9.87 cubic yards. Hope that helps. The number 0.03704 is purely a conversion rate for cubic feet to cubic yards.
( 1 yard = 3 feet )40 / 3 = 13 remainder 1 = 13 yards 1 foot
The area of a room 40ft by 40ft = 1,600 square feet.
3 feet = 1 yard so 40 feet = 13 yards and 1 foot.
3 yards 1 foot is 20 inches greater than 100 inches36 + 36 + 36 + 12 = 72 + 48 = 120It is: 3 yd and 1 ft which equals 120 inches
