Final answer:
A box typically has six faces. If a label is on one side, five faces remain without a label.
Step-by-step explanation:
The student's question inquires about the number of faces on a box that do not have a label, if a label is placed on one side of the box. Since a box typically has six faces (assuming the box is in the shape of a cube), and if one face has a label, then the number of faces without a label would be six minus one. Therefore, there are five faces of the box that do not have labels.
