How Many Cubic Feet Are in a Yard?
One cubic yard is equivalent to 27 cubic feet. This conversion is based on the fact that one yard is equal to 3 feet, with the three-dimensional cubic yard volume therefore being equal to 3 x 3 x 3 = 27.
You might find yourself embarking on a project in your house garden involving concrete, gravel, rock, mulch or other materials and wondering how to measure a cubic yard or how many cubic feet there are in a yard. Wonder no longer, here's what you need to know...
Explanation and diagrams
A foot is 12 inches long, making it exactly a third of a yard. So, if you draw a line on the ground with chalk and it's 1 yard in length, then it's 3 feet long.
1 yard = 3 feet
If you wanted to turn that one dimensional chalk line into a two dimensional area, you could use your line as one side of a square, a yard by a yard in measurement. How many feet are in a square yard? The two dimensions on the flat square (length and width) are each 3 feet long, so the sum is 3 x 3 = 9 square feet in a square yard.
1 square yard = 9 square feet
Now what about if you wanted to turn that flat square into a three dimensional cube? You'd need it to be the same height up as it is across, making it a yard in every direction. So 3 x 3 x 3 (length x width x height) = 27 cubic feet in a cubic yard.
1 cubic yard = 27 cubic feet
So how many cubic feet are in a yard? Well, none if it's a chalk line on the ground, but if it's a cubic yard (sometimes just called a yard for measuring concrete or other materials), then it contains 27 cubic feet.
How many cu ft bags of mulch are in a yard?
Bags of mulch commonly come in sizes from 1 cubic foot to 3 cubic feet, so you may be wondering how many 1, 2 or 3 cubic foot bags of mulch make up a yard (cubic).
- 1 cu ft: 27 bags of mulch in a cubic yard.
- 2 cu ft: 13.5 bags of mulch in a cubic yard.
- 3 cu ft: 9 bags of mulch in a cubic yard.
