In order to see each type of container that the company must load, we need to see the combination in which the total contribution is maximum. To see that we need to find out contribution per feet and rank them. Here contribution per feet = Contribution per container / Volume per container

Maximum space available = 10,000 X 60 X 8 X 8 = 38,400,000
Space required by long containers = 10,560,000
Space remaining = 38,400,000 - 10,560,000 = 27,840,000
Space required by standard containers (2nd ranking) =
23,040,000
Space remaining for Short containers = 27,840,000 - 23,040,000 =
4,800,000
Space required by 1 short container = 640
Number of containers = 4,800,000 / 640 = 7,500 containers
Total number of containers are as follows
1. Long = 3,000 containers
2. Standard = 18,000 containers
3. Short = 7,500 containers
