About Surface Area Calculator

Our Surface Area Calculator helps you determine the total area that the surface of a three-dimensional object occupies. This tool is essential for students, engineers, architects, and anyone working with geometric shapes.

Key Features:

  • Calculate surface area for multiple 3D shapes including cubes, spheres, cylinders, cones, and pyramids
  • Support for different units of measurement (cm, m, in, ft)
  • Instant results with precise calculations
  • Displays the mathematical formulas used
  • Mobile-friendly and responsive design

Common Applications:

  • Academic geometry problems
  • Construction and architectural planning
  • Packaging design and material estimation
  • 3D modeling and computer graphics
  • Manufacturing and material cost calculations

Formulas Used:

  • Cube: SA = 6a² (where a is the edge length)
  • Sphere: SA = 4πr² (where r is the radius)
  • Cylinder: SA = 2πr² + 2πrh (where r is radius, h is height)
  • Cone: SA = πr² + πr√(r² + h²) (where r is radius, h is height)
  • Square Pyramid: SA = a² + 2a√((a²/4) + h²) (where a is base edge, h is height)
