Surface Area Calculator

Calculate surface area of common 3D shapes including cube, sphere, cylinder, and cone. Shows formulas and step-by-step calculations.

How to Use Surface Area Calculator

The Surface Area Calculator computes the total surface area of common 3D shapes. Select a shape (cube, sphere, cylinder, or cone), enter the required dimensions, and get the surface area with the formula shown. Uses standard geometry formulas: 6s² for cube, 4πr² for sphere, 2πr(r+h) for cylinder, and πr(r+l) for cone. Essential for geometry students, engineers calculating material requirements, architects estimating surface coverage, and anyone working with 3D measurements.

Step-by-Step Instructions

  1. Select the 3D shape (cube, sphere, cylinder, or cone)
  2. Enter the required dimensions (side, radius, height, etc.)
  3. Click Calculate Surface Area
  4. View the result with the formula used
