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
you multiply 12 x 40 x .333 and then divide it by 27 which will give you 5.92 or 6 yards of concrete
360 cu ft or if the "4" is inches, not feet, one twelfth of that, ie 30 cu ft
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)
96 cubic feet of concrete
