Suppose the carton of dimensions 1 × 2 × 3 from Table 9.1 was to be stored in a shelf of height 3 and depth 9; how would the values of space efficiency change? What if the shelves were configured to be of height 2? Of height 1?

 

Table 9.1: 

{H, D, W}: {1,2,3} {2,1,3} {3,1,2} {1,3,2} {3,2,1} {2,3,1} 

Efficiency: 0.76 0.57 0.86 0.86 0.76 0.57
