Pseudo Code for Calculating Volume of a Cube

Objective

To calculate the volume of a cube given the length of one edge.

Inputs

• A numeric value representing the length of one edge of the cube.

Outputs

• The volume of the cube.

Steps

1. Start: Begin the program.

2. Input Value:

   • Prompt the user to "Enter the length of one edge of the cube."
   • Store the user input in a variable called edgeLength.

3. Validate Input:

   • Check if edgeLength is a positive number.
     • If edgeLength <= 0:
       • Display "Error: The edge length must be a positive number."
       • Go to Step 2 (Input Value).

4. Calculate Volume:

   • Use the formula for the volume of the cube:
     • volume = edgeLength * edgeLength * edgeLength
   • Alternatively, this can be represented as:
     • volume = edgeLength ^ 3 (using exponentiation).

5. Output Result:

   • Display "The volume of the cube is: " followed by the value of volume.

6. End: Terminate the program.

Pseudo Code Representation

BEGIN
    OUTPUT "Enter the length of one edge of the cube:"
    INPUT edgeLength

    IF edgeLength <= 0 THEN
        OUTPUT "Error: The edge length must be a positive number."
        GOTO Input Value

    volume = edgeLength * edgeLength * edgeLength

    OUTPUT "The volume of the cube is: ", volume
END

Conclusion

The provided pseudo code outlines a clear and straightforward process for taking user input to calculate the volume of a cube. It includes input validation to ensure the input is positive, ensuring that users receive feedback for incorrect entries to enhance user experience.
