Suppose you are laying out a floor stack area with an aisle 15 ft wide to accommodate forklift trucks. All pallets are 48 by 36 and are stored with the 36 side facing the aisle. Assume that each SKU experiences constant demand. Compute a single common lane depth that will be space- efficient for the set of SKUs.

\begin{tabular}{|c|c|c|} \hline SKU & OrderQuantity(pallets) & Stack Height (pallets) \\ \hline A & 36 & 4 \\ \hline B & 16 & 1 \\ \hline C & 34 & 3 \\ \hline D & 24 & 3 \\ \hline E & 30 & 2 \\ \hline \end{tabular}
