You have a truck that needs to be filled up with packages. The trucks packable area is 75 ft³. There are two different size packages: small and large. A small package is 0.25 ft³. A large package is three times the volume of a small package. You have 100 packages in total; 50 packages are small and 50 packages are large. Will they all be able to fit in the truck? If so, how much leftover space is there? If not, how much additional space is needed to fit all 100 packages? Write a code in Matlab to solve this question.
