What is the volume of one cubic yard of concrete?

One cubic yard of concrete is defined as the volume occupied by a cube that measures one yard on each side. To understand this in terms of feet, we need to convert yards to feet. Since one yard equals three feet, the dimensions of this cube in feet are 3 feet by 3 feet by 3 feet.

The volume of a cube is calculated by cubing the length of one side. Thus, if we cube 3 feet, the calculation would be:

3 feet × 3 feet × 3 feet = 27 cubic feet.

Therefore, one cubic yard of concrete equals 27 cubic feet, making this the correct answer. This direct relationship between yards and feet is crucial when working with measurements in construction and material estimation.
