The answer is 576.
360 cu ft or if the "4" is inches, not feet, one twelfth of that, ie 30 cu ft
4 with 7 remaining 55 - 7 = 48 = 12 x 4
x/4 = 12 so x = 4 x 12...
12 x 4 = 48.
(3/4) x 12 = (3 x 12) /4 = 36/4 = 9
Volume of concrete needed = 4 x 12 x 1/3 = 4 x 4 = 16 cubic feet
To calculate the volume of a concrete slab, multiply the length, width, and depth. For a 10 x 12 x 4 slab, the volume is 10 feet × 12 feet × 4 feet = 480 cubic feet. Since concrete is typically sold by the cubic yard, convert cubic feet to cubic yards by dividing by 27. Therefore, you will need approximately 17.78 cubic yards of concrete for the slab.
360 cu ft or if the "4" is inches, not feet, one twelfth of that, ie 30 cu ft
you multiply 12 x 40 x .333 and then divide it by 27 which will give you 5.92 or 6 yards of concrete
100 sqft x (4/12) 33.33 cubic ft. Of concrete.
about how much to pour a concrete slaba 12 x 14'
800lbs
12 x 12 feet, 4 inches deep: 1.8 cubic yards, minimum.
12 ft x 10 ft x .333 ft (4 in) = 39.96 cu ft. You need enough concrete for 40 cubic ft.
12 ft x 10 ft x .333 ft (4 in) = 39.96 cu ft. You need enough concrete for 40 cubic ft.
That depends on how deep (thick) you need it to be. You'll need 1 yard of concrete for every 3/4 inch of thickness of the pad.
10-ft x 30-ft x 4-in = 100 cubic ft.That slab weighs 3.7 times as much as 1 "yard" of concrete. (rounded)
