Evelina is using a wooden block as a stamp to make decorative wrapping paper. The wooden block measures \(3\) cm by \(3\) cm by \(4\) cm and Evelina is stamping with one of the \(3\) cm by \(3\) cm square faces of the block.
Evelina creates a row of \(10\) stamped squares with a gap of \(0.5\) cm in between each square. Determine the length of this row.
Evelina has a square piece of wrapping paper with side length \(77.5\) cm.
