152/(6*6) = 4.22... (recurring) feet.
53 and 1/3 cubic feet, concrete is normally sold buy the cubic yard, this would be 1.975 cubic yards. Figure on 2.25 CU yards to be safe. You do not want to run short when pouring concrete.
81 Square feet.
A Yard of Concrete? what unit is this? Linear? Cubic? Front yard or back? I suppose it is a Cubic Yard of Concrete. The answer is (36/3)*9 = 108sf
147 cubic feet of cement are required.
If you made a sidewalk about 2.5' wide it would be about 13' long.
Type your answer here... I HAVE 165.50 DIA DRILLED PIERS 3'-0" IN LINEAR FEET THAT I NEED TO CONVERT TO CUBIC YARDS OF DRILLED PIER CONCRETE.
Volume = 12 cubic feet = (12 / 27 ) 0.444 cubic yard
One cubic yard every 4.5 linear feet
Type your answer here... 250,000 cubic yards
58 x 4 =234 sq feet x .33 = 76.56 cubic feet / 27 = 2.835 cubic yards.
That is 53x1 x 8/12 = 35.33 cubic feet. That is 1.31 yards and weighs 5300 pounds
Well, you make a sidewalk from concrete, not just cement. Concrete consists of cement, sand, gravel and water. You will need 5.5 cubic feet of concrete. A standard sidewalk grade of concrete would be 1 part cement, 2 parts sand, 3 parts gravel- so the sidewalk needs 0.91 cu ft of cement- about 87 pounds worth- plus sand and gravel. If you want to buy the premixed bags of concrete (like Sacrete), you will need about 17 of the 40 pounds bags. And you did not ask, but 3 inches is kind of skinny- I would go for at least a 4 inch thick sidewalk.
