11) At the Writing Factory, the assembly line produces 225 pencils in a batch. The pencils are packaged in boxes with 20 each. If 3 batches are made in one day, how many pencils will be leftover at the end of it?

\( \left. \begin{array} { l }{ f \circ f ) ( x ) = f ( 2 x ^ { 2 } - x ) } \\ { = 2 ( 2 x ^ { 2 } - x ) ^ { 2 } - ( 2 x ^ { 2 } - x ) } \\ { = 2 ( 4 x ^ { 2 } - 4 x + x ) - 2 x ^ { 2 } + x } \\ { = 8 x ^ { 2 } - 8 x + 2 x - 2 x ^ { 2 } + x } \\ { = 6 x ^ { 2 } - 6 x + 1 } \end{array} \right. \)

Simplify. \[ \left(v^{3}\right)^{2} \]
