To find the total linear inches, we need to understand what you mean by "linear inches". Do you want:
* The perimeter of the rectangle? In this case, you'd add up the length of all the sides: 2(19 inches) + 2(11 inches) = 60 inches.
* The total length of all the edges of the rectangular box? This would be 4(19 inches) + 4(11 inches) + 4(10 inches) = 120 inches.
* Something else? Please clarify your request.
