approx. 74 yards Sorry, Dabar, but I think you have not accounted for the conversion of cu. feet to cubic yards...my calculations are as follows...... 40 X 17 is equal to 680 cubic FEET of area. You take the 680 and divide by 27 to get the cu. YARDS of concrete. (25.1 cu. yds) Then because you only want the slab 4 inches thick, you multiply by .33 (or 8.25 cu. yards of concrete) Then you allow 10 % for waste or shortage....(make this about a yard...so, 8.25 and one for waste/shortage is equal to 9.25 cu. yards of Concrete for this project)
"capacity of a concrete truckis,the large usual sixe is 9 yards,the smaller are about 3 yards" Actually over the years the size of mixer drums has increased You will notice the large the drum the more axles the truck has plus it depends on what make a mixer it is 1) London 2) Jaeger 3) Rex The early 3 axle trucks with a rex mixer carried 5 cu yards That increased to 7 cu yards London and Jaeger drums carried 8 cu yards On trucks with 3 axles and a tag (4th axle that trails the truck) carried 12 yards or 10m3 The newer 5 axle trucks usually hold 14-16 cu yards Please understand that 1 m3 = 1.3 cu yards 1 cu yard/27 cu ft of 20 mpa concrete at a 3" slump weights - 3400 lbs Hope this helps you
There are 12 inches in one foot and three feet in a yard. So the answer would be 318 inches.
The Tower in 324 meters tall or 354,3 yards
60 feet=720 inches 60 feet=20 yards 1 foot=12 inches 1 yard=3 feet
It depends on the size of the concrete blocks
