Paulina asks:

Do you know if there is a general rule of thumb for the McKee formula interpreting the depth of a box?

If the depth is in the 20” range, how much does that reduce the expected McKee target?
And the same for a small depth (example: 4”).

George Maltenfort in his Corrugated Shipping Containers: An Engineering Approach introduces a graph on page 78 that shows when the depth is 20 inches on an RSC there is a loss of about 40 pounds in compression. When the depth is 4 inches the loss in compression is only 10 pounds. If you don’t have a copy of George’s book you can find it on Amazon.com.
