A new sidewalk will be 4 feet wide 200 feet long and filled to a depth of 6 inches with concrete. how many cubic yards of concrete are needed?
Convert all to (linear) yards
4ft = 1 1/3 yds
200 ft = 200/3 = 66 2/3 yds
6 inches = 1/6 yds
Multiplication of fractions
1 1/3yds X 66 2/3yds x 1/6yd =
4/3 yds X 200/3 yds x 1/6 yds =
800 / 54 cu.yds
= 14.8148 cu.yds.

How much cement is needed to build a sidewalk that is 132 inches long 24 inches wideand 3 inches think?
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.
How many cubic feet are needed to pour a 40 ft long by 3 ft wide by 4 inches thick side walk?
To calculate the volume of concrete needed for the sidewalk, first convert the 4 inches thickness to feet (4 inches = 1/3 feet). Then, multiply the length (40 ft) by the width (3 ft) by the thickness in feet (1/3 ft) to get the total volume in cubic feet. This comes out to be 40 ft * 3 ft * 1/3 ft = 40 cubic feet of concrete needed for the sidewalk.

How to calculate how much concrete is needed for a project?
To calculate the amount of concrete needed for a project, you need to determine the volume of the area to be filled with concrete. This can be done by multiplying the length, width, and height of the area. Once you have the volume, you can then calculate the amount of concrete needed by dividing the volume by the coverage area of one cubic yard of concrete. This will give you the total number of cubic yards of concrete needed for the project.

Should there be wire mesh in sidewalk?
Wire mesh should always be placed in a sidewalk. The wire mesh reinforces concrete that is only strong in compression. The concrete expands and contract in the summer and winter and the mesh will minimize cracking. It also helps when your neighbor drives his pick up truck across your sidewalk. Whenever a concrete road/bridge deck is placed reinforcing steel or heavy mesh is in it. The state agency doesn't do it unless it's needed.
