In inches, how long is a piece that was not cut from the sheet metal if it remains at 15 3/16 inches long?

The piece that remains at 15 3/16 inches long is referred to as the remaining piece because it represents the portion of the sheet metal that has not been cut. This terminology is commonly used in trades and manufacturing contexts to describe the part of a material that is left after a cut has been made.

When a sheet metal is cut, it typically leaves behind some material that retains its original length, which in this case is 15 3/16 inches. This indicates that the piece is complete and has not undergone any alterations that would affect its length. Understanding this concept is essential in trade work where precise measurements are critical for planning and execution.

The other terms provided do not accurately describe the state of the piece. The term "cut-off piece" would suggest that it has been separated from a larger section, while "whole sheet" implies that it has not been altered at all. "Unable to determine" is not applicable since the length of the remaining piece is explicitly stated. This clarity reinforces the understanding that the correct choice reflects the definition of what remains after cuts have been made.
