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
A cubic yard = 3' x 3' x 3' = 27 cubic feet = 3888 cubic inches
about 432 cubic inches
147 cubic feet of cement are required.
Multiply length times width. IF your driveway was 1 foot thick that would be the number of cubic feet of concrete. HOWEVER- it is only 4 inches thick. That is .33 ft (one third of a foot). So take your answer you got from multiplying LxW, and divide by 3. That will be the number of cubic feet of the driveway's volume.
Essentially, you need three and a third cubic yards of concrete to replace that quantity to those measurements - so if the cost of a cubic yard of concrete is 30, multiply it by 3.333 and you get 100
Not square yards, but Approx. 5.24 cubic yards 54'2" = 650" x 7'10" = 94" x 4" = 4" = 244,400 cubic inches / 46,656 cubic inches = 1 cubic yard (36" x 36" x 36")= 5.24 cubic yards
$70 - $100 per cubic yard depending on supplier.
387 cubic feet. This is because 43x18x0.5 (as six inches is 1/2 of a foot) =387.
A cubic yard is 46,656 cubic inches. Spread to a thicknes of 5 inches, a cubic yard of concrete covers 9332.1 square inches, which is 64.8 square feet.
9.3 cubic yards of cement is required for this slab.
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.
8 x 8 x 16 = 1,024 cubic inches.
4"x16'x32' = 2.370370... cubic yards
Slightly less than 1. 5x10 is 50 square feet. If the pad was 6 inches thick that would equal 25 cubic feet. There are 27 cubic feet in 1 cubic yard.
