Calculating the surface area of a three-dimensional object, such as a sphere or cylinder, is essential in various fields, including mathematics, engineering, and design. To streamline this process, we can utilize a simple yet efficient calculator built. This article will guide you through the usage, formula, examples, FAQs, and conclusion of a skin area calculator.

How to Use

To utilize the skin area calculator, follow these steps:

  1. Input the necessary dimensions of the object.
  2. Click on the “Calculate” button.
  3. The calculator will then compute the surface area based on the provided dimensions.
  4. Review the result displayed on the screen.


The formula for calculating the surface area of different geometric shapes is as follows:

  1. Sphere: Surface Area = 4πr²
  2. Cylinder: Surface Area = 2πrh + 2πr²
  3. Cube: Surface Area = 6a²
  4. Cuboid (Rectangular Prism): Surface Area = 2lw + 2lh + 2wh

Example Solve

Let’s calculate the surface area of a sphere with a radius of 5 units.


  • Radius (r) = 5 units

Using the formula for the surface area of a sphere:

Surface Area = 4πr²

Substituting the given value:

Surface Area = 4π(5)²

Surface Area ≈ 314.16 square units
