What is one-half the cube of n?

One-half the cube of ( n ) is expressed mathematically as ( \frac{1}{2} n^3 ). This means you first calculate the cube of ( n ) (which is ( n \times n \times n )), and then multiply the result by ( \frac{1}{2} ). Thus, if ( n = 2 ), for example, then one-half the cube would be ( \frac{1}{2} (2^3) = \frac{1}{2} \times 8 = 4 ).
