One yard of concrete will cover approximately 90 square feet at a depth of 3-1/2". At an even 3-1/2", you will need just over 3 yards. This does not allow for any footings, turndowns, or a thicker slab.
its about 12x5x67 respectively
6 inches = 1/2 footVolume = (surface area) x (depth) = 450 x 1/2 = 225 cubic feet = 81/3 cubic yards.
It depends on the depth required

How much does it cost to seal a concrete patio
Outdoor patio sets range from very low cost ones (Amazon, Target, Walmart, Sams) to very expensive ones that How much does it cost for a concrete patio
its about 12x5x67 respectively
That depends on how thick you want it. Multiply 18ft * 18ft * thickness (in units of feet). That will give you your volume in cubic feet. To convert it to cubic yards divide your answer by 27.
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.
96 cubic feet of concrete
a lot.
Try to do as little as possible of a slope, so you won't feel it but so it has a slope
0.246914 cu. yards (6.666667 cu. ft ) of concrete is needed.
First find out how much concrete is needed for your project thwn do the calculations.
The amount of concrete needed for a fence post depends on the size and depth of the hole. Typically, a 50 lb bag of concrete mix is enough for one standard fence post.
Approximately 12.35 Cubic Yards.
