Assignment

You are a software engineer for a transcontinental shipping company that ships crates across the ocean on large cargo ships. Your company needs you to write a program to figure out some metrics on both shipping crates that will be stored on the ships, and storage rooms that will store the crates. Specifically they need you to find the volume, surface area, and spatial diagonal length of the crates and storage rooms. They also need you to figure out how many crates can fit into the storage rooms.

Write a complete program that:

1. Prompts the user to enter the dimensions of a shipping crate and reads in the dimensions and stores them into doubles. The dimensions you will need to get are:

   • Length of the storage shipping crate.
   • Width of the storage shipping crate.
   • Height of the storage shipping crate.

2. Calculates the volume of the rectangular prism entered in (1). (See equation below)

3. Calculates the surface area of the rectangular prism entered in (1). (See equation below)

4. Calculates the diagonal of the rectangular prism entered in (1). (See equation below)

5. Prompts the user to enter the dimensions of the storage space for shipping crates and reads in the dimensions and stores them into doubles. The dimensions you will need to get are:

   • Length of the storage space for the shipping crates.
   • Width of the storage space for the shipping crates.
   • Height of the storage space for the shipping crates.

6. Calculates the volume of the rectangular prism entered in (5). (See equation below)

7. Calculates the surface area of the rectangular prism entered in (5). (See equation below)

8. Calculates the diagonal of the rectangular prism entered in (5). (See equation below)

9. Finds out how many shipping crates can fit in the storage space. (See equation below)

10. Outputs the answers from (2), (3), (4), (6), (7), (8), and (9) nicely using iomanip. See the Example Executions for example formatting.

Equations

Volume of a rectangular prism:

$$volume = w * h * l$$

Surface area of a rectangular prism:

$$surfaceArea = 2(w * l + h * l + h * w)$$

Space diagonal of a rectangular prism:

$$diagonal = √(l^2 + w^2 + h^2)$$

How many shipping crates can fit in a storage space:

$$total = ⌊spaceL / crateL⌋ * ⌊spaceW / crateW⌋ * ⌊spaceH / crateH⌋$$

Example Program Interactions

An example of an interaction with your program is shown below, your output should match these examples exactly.

Example 1

Alexs-iMac:as3 alex$ g++ -Wall -pedantic as3.cpp
Alexs-iMac:as3 alex$ ./a.out
SHIPPING CRATE
Enter length of the shipping crate
10

Enter width of the shipping crate
10

Enter height of the shipping crate
10


STORAGE SPACE
Enter length of storage space
100

Enter width of storage space
100

Enter height of storage space
100


+-------+---------+--------+--------+------------+--------------+----------+
| TYPE  | LENGTH  | WIDTH  | HEIGHT | VOLUME     | SURFACE AREA | DIAGONAL |
+-------+---------+--------+--------+------------+--------------+----------+
| Crate | 10.0    | 10.0   | 10.0   | 1000.0     | 600.0        | 17.3     |
| Space | 100.0   | 100.0  | 100.0  | 1000000.0  | 60000.0      | 173.2    |
+-------+---------+--------+--------+------------+--------------+----------+

1000.0 crates can fit in the storage space.

Example 2

Alexs-iMac:as3 alex$ ./a.out
SHIPPING CRATE
Enter length of the shipping crate
7.7

Enter width of the shipping crate
2.4

Enter height of the shipping crate
4.3


STORAGE SPACE
Enter length of storage space
90.5

Enter width of storage space
87.2

Enter height of storage space
40.44


+-------+---------+--------+--------+------------+--------------+----------+
| TYPE  | LENGTH  | WIDTH  | HEIGHT | VOLUME     | SURFACE AREA | DIAGONAL |
+-------+---------+--------+--------+------------+--------------+----------+
| Crate | 7.7     | 2.4    | 4.3    | 79.5       | 123.8        | 9.1      |
| Space | 90.5    | 87.2   | 40.4   | 319136.3   | 30155.6      | 132.0    |
+-------+---------+--------+--------+------------+--------------+----------+

3564.0 crates can fit in the storage space.

See CodeGrade for more examples.

Note: The line breaks after the inputs in the example output formatting above are the default ones C++’s cin and getline() automatically apply after reading an input from the user. CodeGrade supplies input in a different manner (Linux redirection) to programs so in CodeGrade's auto tests there will not be line breaks after the inputs.
