Pseudo Code for Cube Calculations

This pseudo code outlines the steps to calculate the surface area of one side of a cube, the total surface area of the cube, and its volume based on the length of one edge of the cube.

Main Points

1. Input

   • Read the length of one edge of the cube (edge_length).

2. Calculations

   • Calculate the surface area of one side.
   • Calculate the total surface area of the cube.
   • Calculate the volume of the cube.

3. Output

   • Display the results.

Pseudo Code

BEGIN

    // Step 1: Input
    DECLARE edge_length AS FLOAT
    PRINT "Enter the length of one edge of the cube:"
    INPUT edge_length

    // Step 2: Calculations
    DECLARE surface_area_one_side AS FLOAT
    DECLARE total_surface_area AS FLOAT
    DECLARE volume AS FLOAT

    // Calculate the surface area of one side
    surface_area_one_side = edge_length * edge_length

    // Calculate the total surface area of the cube (6 sides)
    total_surface_area = 6 * surface_area_one_side

    // Calculate the volume of the cube
    volume = edge_length * edge_length * edge_length

    // Step 3: Output
    PRINT "Surface area of one side: ", surface_area_one_side
    PRINT "Total surface area of the cube: ", total_surface_area
    PRINT "Volume of the cube: ", volume

END

Key Variables

• edge_length: The length of one edge of the cube.
• surface_area_one_side: The area of one face of the cube.
• total_surface_area: The total area of all six faces of the cube.
• volume: The total volume enclosed by the cube.

Explanation

• Input Section: The user is prompted to provide the length of one edge of the cube.
• Calculation Section:
  • The surface area of one side is calculated by squaring the edge length.
  • The total surface area multiplies the surface area of one side by 6.
  • The volume is calculated by cubing the edge length.
• Output Section: The program displays the calculated surface area of one side, the total surface area, and the volume of the cube.

This structure effectively communicates the logic of the program while remaining accessible and easy to understand.
