<p>In<a>math</a>, the cube of a<a>number</a> is found by multiplying the number by itself three times. It is expressed as \(n^{3} = n \times n \times n\), where n is the<a>base</a>number. This is also called the cube of a number. The cube in math is related to a 3D shape with all sides equal. When a positive number is cubed, the result is always positive, and when a<a>negative number</a>is cubed, the result will always be negative. </p>
