Have an understanding:
Cubic feet means the volume of a cube.
In a cube, the volume is calculated by multiplying the length, width, and height. The length, width, and height of a cube is the same. So, if the length is 2, then the volume would be 2x2x2=8.
1 yard = 3 feet.
If the cube is 1 cubic yard, then its length, width, and height are all 3 feet.
To find its volume, do 3 x 3 x 3 = 27.
The answer is 27 cubic feet.
