A thread died for this.

Number of unit cubes: [math]n^3[/math]
Number of unit cubes with 3 faces painted: [math]\begin{cases} 0 \quad\text{if }n \,=\, 1 \\ 8 \quad\text{otherwise} \end{cases}[/math]
Number of unit cubes with 2 faces painted: [math]\begin{cases} 0 \quad\text{if } n \,=\, 1 \\ 12 \,\left( n \,-\, 2 \right) \quad\text{otherwise} \end{cases}[/math]
Number of unit cubes with 1 face painted: [math]\begin{cases} 0 \quad\text{if } n \,=\, 1 \\ 6\,\left( n \,-\, 2 \right)^2 \quad\text{otherwise} \end{cases}[/math]
Number of unit cubes with 0 faces painted: [math]\begin{cases} 0 \quad\text{if } n \,=\, 1 \\ \left(n \,-\, 2 \right)^3 \quad\text{otherwise} \end{cases}[/math]
Total face area of prop cubes not painted: [math]\begin{cases} 0 \quad\text{if } n\,=\, 1 \\ 3 \,\times\, 8 \,+\, 4 \,\times\, 12 \,\left( n \,-\, 2 \right) \,+\, 5 \,\times\, 6\,\left( n \,-\, 2 \right)^2 \,+\, 6 \,\times\, \left(n \,-\, 2 \right)^3 \quad\text{otherwise} \end{cases}[/math]

This is middle school tier bullshit.
