(15,080 cubic inches) / (1,728 cubic inches per cubic foot) = 8.727 cubic feet (rounded)
(8.727 cubic feet) / (27 cubic feet per cubic yard) = 0.323 cubic yard (rounded)
160 cubic inches / (1/8 inches) = 160*8 = 1280 sq inches
1 sq. feet = 144 sq. inchesSo,392 sq. feet = 144 * 392 sq inches = 56448 sq. inchesVolume of cement needed = 56448 sq inches * 4 inch = 225792 cubic inches225792 cubic inches = 1568 cubic feet
It would take 676 cubic feet of cement for a patio of that size.
13 1/3 cubic yards
25 feet is equal to 300 inches. The radius of a hole is half its diameter, which equals 4 inches. The volume of the cylinder is given by the formula v = [Pi]r2h, so the volume of your hole is 3.14 * 16 * 300 = 15080 cubic inches. There are 1728 cubic inches to the cubic foot, so you'll need about 8.75 cubic feet of concrete, which is about a third of a yard. (More exactly, that's a cubic yard, but concrete guys just say "yard.")
0.3 cubic meter cement mortar consumes.
How much cement sand and stone do you need for 1 cubic meter of concre

Concrete is a mixture of cement , sand, gravel and water. A cubic yard of concrete is 3' x 3' x 3' . That's 3x3=9x3=27 . 27 cubic feet = 1 cubic yard . So it's 27 feet divided by 3 inches equals 108 sq ft!
