To calculate the volume of concrete needed, first convert all measurements to feet. The sidewalk is 3 feet wide (36 inches), 0.33 feet thick (4 inches), and 60 feet long. The volume in cubic feet is calculated as: 3 ft (width) x 0.33 ft (thickness) x 60 ft (length) = 59.4 cubic feet. To convert cubic feet to cubic yards, divide by 27; thus, you need approximately 2.2 cubic yards of concrete.
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.
Cubic feet of concrete required = 32 x 3 x 0.25 = 24 cu. ft 1 cu yd = 27 cu ft Answer: 24/27 cu yards = 0.89 cu yards.
A concrete sidewalk typically takes about 24 to 48 hours to harden enough for light foot traffic. However, it can take up to 28 days for the concrete to fully cure and reach its maximum strength. Factors such as temperature, humidity, and the mix used can affect the curing time. It's best to avoid heavy loads on the sidewalk until it has fully cured.
To calculate the volume of a concrete slab that is 40 feet long, 60 feet wide, and 6 inches thick, first convert the thickness to feet (6 inches = 0.5 feet). The volume in cubic feet is 40 x 60 x 0.5 = 1,200 cubic feet. To convert cubic feet to cubic yards, divide by 27 (since there are 27 cubic feet in a cubic yard). Thus, 1,200 cubic feet is approximately 44.44 cubic yards.
Not square yards, but Approx. 5.24 cubic yards 54'2" = 650" x 7'10" = 94" x 4" = 4" = 244,400 cubic inches / 46,656 cubic inches = 1 cubic yard (36" x 36" x 36")= 5.24 cubic yards
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.
You will need a minimum of 2.42 cubic yards of cement.
If you made a sidewalk about 2.5' wide it would be about 13' long.
16 ft * 47 ft * 4 inches =16/3 yards * 47/3 yards * 4/36 yards = 9.3 yards approx.
4.23776 cubic yards
Volume = 12 cubic feet = (12 / 27 ) 0.444 cubic yard
To calculate the amount of cement needed, first convert the dimensions of the sidewalk into cubic yards. The sidewalk's volume is ( \frac{4}{12} ) feet thick × 3 feet wide × 40 feet long = 40 cubic feet. Since there are 27 cubic feet in a cubic yard, the volume in cubic yards is ( \frac{40}{27} \approx 1.48 ) cubic yards. At $76 per cubic yard, the total cost would be approximately ( 1.48 \times 76 \approx 112.48 ).

That is about 135 cu ft., or 5 yards
each cu.yard of concrete is equal to 4 inches thick X three ft. X three ft. X 9 So 3 ft wide x 3 ft. long is equal to 4 ft wide X 2.25 ft long. Therefore 34 ft long is just over 15 of these 2.25 increments. So since there are 9 increments in a yard, you'd need 1 and 2/3 (1.66) cu.yards. for your sidewalk. Concrete is usually $85+-/yd so you might be able to only purchase $140 worth of concrete and do it with your buddies. It will be the last time they come to your house to help with a project though.
You will need 3.7 cubic yards of cement.
