Looking at the table, we can see that all width values are the same, all length values are the same and all height values are the same.
Therefore, if we use the variable x to represent the first column: "line drawing measurement", variable y for the second column: "3D model" and variable z for the third column: "final measurement", we can create the following parent functions:
This way, we can represent that the values of "3D model" and "final measurement" are always the same values of "line drawing measurement", and that is valid for all three dimensions: width, height and length.
