The mathematical expression of the statement can be written as:
![(n^3)/(9)-6+12](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ov6vnfrpivf7sterc2oyi7ticp8n3wkde6.png)
Evaluating the expression when
![n=3](https://img.qammunity.org/2020/formulas/mathematics/high-school/bniwkmpbbnwkxheuhsxe8uo03pkym9d5cm.png)
![=(3^3)/(9)-6+12](https://img.qammunity.org/2020/formulas/mathematics/middle-school/zitr5hoggmmf0oy4kgiapwljtzxgq77030.png)
![=(27)/(9)-6+12](https://img.qammunity.org/2020/formulas/mathematics/middle-school/y61fyvj5vob2voq6u5asw5m1pz8y9zoxyh.png)
