This tool calculates the surface area of various geometrical shapes to provide accurate measurements for your projects.

Surface Area Calculator

How to Use the Calculator

Select the geometric shape from the dropdown menu and enter the required dimensions. Click “Calculate” to get the surface area result displayed in the result field.

Explanation

The calculator computes surface area based on standard geometric formulas:

  • Cube: 6 × side2
  • Rectangular Prism: 2 × (length × width + width × height + height × length)
  • Cylinder: 2π × radius × (radius + height)
  • Sphere: 4π × radius2

Limitations

This calculator only supports basic shapes: cube, rectangular prism, cylinder, and sphere. Ensure all dimensions are entered as positive numbers. Small rounding errors may occur due to the precision limitations of floating-point arithmetic in JavaScript.
