Question
The code needs to be complete
BOX
The program should be able to create (instantiate) three types of boxes. The first box would use the default constructor. The second box would be a cube and only need one parameter. The third box would be a rectangular solid and you will send in three parameters to the constructor
You should be able to perform the following calculations on your box: surface area of the entire box and volume. Furthermore, you should be able to make your box larger and smaller in the following two different ways:
• Specify by how much larger (multiplier) you would like to enlarge each dimension of the object. For example, makeLarger(2) would multiply the length, width, and height of the box by 2.
• Specify the specific amount you would like to add to each dimension of the box. For example, makeLarger(1, 3, 5) would add 1 to the length, 3 to the width, and 5 to the height of the box.
Be sure to include methods for the following tasks:
1. Constructors (three)
2. Calculate and return the volume
3. Calculate and return the surface area
4. Enlarge the box by multiplying each side by a number
5. Enlarge the box by adding a number to each side
6. Output the dimensions
Demonstrate that your program works properly. You will need to test all of the constructors and all of the methods in your class. Display all results to two decimal places.
Input and output should be done with Dialog and Message boxes. Your program should be well documented internally and externally.
