Length x width x depth(thickness) divided by 27. (measurements in feet.) Most concrete is poured 4 inches thick which is .33 feet, so you can use .33 for the depth(thickness). Here's how it works: You are going to pour a 40 foot driveway that is 10 foot wide and it's going to be a standard 4 inches thick. 40 x 10 x .33 divided by 27 (27 cubic feet in a yard of concrete.) The answer is 4.95 cubic yards. I would order 5 yards and it's going to be close. Always order just a little extra. Also, In my area, a full truck load is 9 cubic yards. They used to haul 10, but DOT has reduced weight to 9 yards per truck.
Volume in cubic feet of an object is found by finding the area (length x width for a rectangle; pi x radius squared for a cylinder) of an object in square feet and multiplying that area by the height in feet.
Example:
Volume of a box having length 4 ft, width 3 ft, and height 2 ft: (4 ft x 3 ft) x 2 ft = 12 ft2 x 2 ft = 24 ft3
Volume of a cylinder having a radius of 3 ft and a height 2 ft (3.14 x 3 ft x 3 ft) x 2 ft = 28.26 ft2 x 2 ft = 56.5 ft3 (approx)
If 1 cubic yard = 27 cubic feet, then 4 cubic yards = 108 cubic feet.
Start with a conversion factor. An "old timer's" view is that a cubic foot of dry sand weighs about 125 pounds. There are 3 feet in a yard. There are 3 x 3 or 9 square feet in a square yard. There are 3 x 3 x 3 or 27 cubic feet in a cubic yard. As there are 27 cubic feet in a cubic yard and there are 125 pounds to a cubic foot of our dry sand, there are 27 x 125 pounds of dry sand per cubic yard, or 3,375 pounds of dry sand per cubic yard. (Yes, there are that many.) There are 2,240 pounds in an Imperial ton. There are 3,375 divided by 2,240 Imperial tons in a cubic yard of dry sand, or right at 1.5 Imperial tons of dry sand per cubic yard. To convert cubic yards of dry sand to Imperial tons, multiply the number of cubic yards of dry sand by 1.5 and your answer will appear. Every time.
There are 27 cubic feet in one cubic yard.
You need 7500 cubic feet of sand, say 150 long x 100 wide = 15000 x .5 (half a foot)deep=7500. In order to figure this you need to know how many cubic feet are in a ton of sand and we don`t have that, but there is a way around it. Typically sand, gravel and top soil etc. is sold by contractors by the yard or cubic yard. So look at it this way 7500 cubic feet divided by 27 cubic feet (3x3x3=27) in one cubic yard and your answer is 278 yards or cubic yards of sand.
There are 27 cubic feet in one cubic yard.
1 cubic yard = 27 cubic feet
There are 27 cubic feet in a cubic yard.
Nine 3 cubic feet bags equals one cubic yard. There are 27 cubic feet in one cubic yard. 27/3=9
1 cubic yard = 27 cubic feet.
None. 1 cubic yard = 27 cubic feet
There are 27 cubic feet in a cubic yard. So, if you have a yard of granite, you would have 27 cubic feet of granite.
1 kg = 2.2 pounds sand weighs 100 pounds per cubic foot 2.2/100 = .022 cubic feet one cubic yard = 27 cubic feet .022/27 = 0.00081 cubic yards
