Surface Area Calculator
Result
Basic Shape Surface Areas Calculator: clearly defined inputs, output units, and assumptions.
Formula
- Reports four distinct shapes from supplied positive dimensions. Cone and cylinder include their circular bases. All dimensions must use the same length unit. Formula: sphere 4πr²; cube 6a²; closed cylinder 2πr(r+h); closed right cone πr(r+√(r²+h²)).
- The main inputs are Radius, Cube side length, Height. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Surface Area
- Radius: 3 units
- Cube side length: 4 units
- Height: 5 units
For Radius (units) = 3, Cube side length (units) = 4, Height (units) = 5, primary result = 113.0973355.
