Introduzione
Surface Area Calculator — Calculate surface area for cubes, spheres, and cylinders. Enter Shape, A (side / radius), B (height, cylinder only) to get an instant, accurate result.
Formula
Cube: 6×side². Sphere: 4π×radius². Cylinder: 2πr×(r+h), where r is radius and h is height.
Passo dopo passo
- Enter the Shape.
- Enter the A (side / radius).
- Enter the B (height, cylinder only).
- Click Calculate to see your result instantly.
Esempio pratico
Example: With Shape = cube, A (side / radius) = 3, B (height, cylinder only) = 0, the Surface Area Calculator gives Surface Area: 54.
Domande Frequenti
Which shapes are supported?
Cube, sphere, and cylinder.
Does the cylinder formula include both circular ends?
Yes, along with the curved side.
What inputs does the Surface Area Calculator need?
You'll need to provide: Shape, A (side / radius), B (height, cylinder only). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Surface Area Calculator?
The Surface Area Calculator applies the formula exactly as calculated — Cube: 6×side². Sphere: 4π×radius². Cylinder: 2πr×(r+h), where r is radius and h is height. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Surface Area Calculator free to use?
Yes, the Surface Area Calculator is completely free, requires no signup, and runs instantly in your browser.
Informazioni su Calcolatore di superficie
The Surface Area Calculator uses a real, verifiable formula — Cube: 6×side². Sphere: 4π×radius². Cylinder: 2πr×(r+h), where r is radius and h is height. — so results are accurate every time, not an approximation.
