The expression "n³" represents a mathematical operation known as "cubing." It means multiplying a number, denoted as n, by itself three times: n × n × n. This operation results in the volume of a cube with side length n. For example, if n is 2, then 2³ equals 8, which is the volume of a cube with each side measuring 2 units. Cubing is a fundamental concept in algebra and is often used in various fields, including geometry, physics, and engineering. Understanding n³ helps in solving problems related to three-dimensional space and can be applied in real-world scenarios, such as calculating the capacity of containers.
