Formulas Used

Explanation and derivation of mathematical formulas:

Surface area calculation

The surface area (A) of the snub cube is calculated using the formula:

    A = 2 * a^2 * (3 + 4 * √3)

where a is the edge length of the snub cube.

Volume calculation

The volume (V) of the snub cube is determined by the formula:

    V = a^3 * (3 * √t - 1 + 4 * √t + 1) / (3 * √(2 - t))

where t is a constant specific to the snub cube (t ≈ 1.839286755214161) and a is the edge length.

Radius calculations

The calculations for the circumsphere radius (rc) and midsphere radius (rm) are derived as follows:

  • Circumsphere radius (rc):

            rc = a * √((3 - t) / (4 * (2 - t)))
  • Midsphere radius (rm):

            rm = a * √(1 / (4 * (2 - t)))

Surface-to-volume ratio formula

The surface-to-volume ratio (A/V) is computed using the formula:

    A/V = 2 * (3 + 4 * √3) / (V / A)

It provides insight into the relationship between the surface area and the volume of the snub cube.

Calculation Process

Detailed breakdown of how calculations are performed using JavaScript

The Snub Cube Calculator uses JavaScript functions to calculate various geometric properties based on user input. Here is a breakdown of the calculation process:

  1. Input Retrieval: JavaScript retrieves user input values from the HTML input fields for edge length (a), surface area (A), volume (V), circumsphere radius (rc), midsphere radius (rm), and surface-to-volume ratio (A/V).
  2. Validation: The calculator checks if exactly one input value is provided. If no value or more than one value is entered, an alert message prompts the user to enter exactly one value.
  3. Calculation Formulas: Depending on the input parameter, JavaScript applies the corresponding formulas to calculate the other parameters:
    • Surface Area (A): Calculated using 2 * a^2 * (3 + 4 * √3).
    • Volume (V): Calculated using a^3 * (3 * √t - 1 + 4 * √t + 1) / (3 * √(2 - t)).
    • Circumsphere Radius (rc): Calculated using a * √((3 - t) / (4 * (2 - t))).
    • Midsphere Radius (rm): Calculated using a * √(1 / (4 * (2 - t))).
    • Surface-to-Volume Ratio (A/V): Calculated using 2 * (3 + 4 * √3) / (V / A).
  4. Rounding Functionality: After calculating each parameter, JavaScript rounds the results to the specified number of decimal places chosen by the user. This ensures that the output is precise and manageable.
  5. Display Results: Finally, JavaScript updates the HTML input fields with the calculated values, displaying them to the user for review.

Explanation of rounding functionality

Roundings in JavaScript are performed using the Math.round() function, which rounds a number to the nearest integer. To round to a specific number of decimal places, the calculation involves multiplying the number by a power of 10, rounding it, and then dividing it back by the same power of 10. This ensures the desired precision in the results displayed to the user.
