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