Surface Area Calculator
Calculate total surface area and volume for a rectangular prism, cube, sphere, cylinder, or cone.
Formula
Each solid uses its own exact geometry: prism 2(lw+lh+wh), sphere 4pi r2, cylinder 2pi r(r+h), cone pi r(r+sqrt(r2+h2)), with matching volume formulas.
About the Surface Area Calculator
Calculate total surface area and volume for a rectangular prism, cube, sphere, cylinder, or cone. Geometry and construction calculators apply the named dimensional formula and, where available, material or waste allowances.
How the Surface Area Calculator Works
Each solid uses its own exact geometry: prism 2(lw+lh+wh), sphere 4pi r2, cylinder 2pi r(r+h), cone pi r(r+sqrt(r2+h2)), with matching volume formulas.
The calculation runs in your browser. Submitted values are validated for the required numeric range, data shape, units, and method-specific restrictions before a result is shown.
Required Inputs
- Solid shape (required) Options: Rectangular prism, Cube, Sphere, Cylinder, Right circular cone
- Length or cube side (optional)
- Width (optional)
- Height (optional)
- Radius (optional)

How to Use the Calculator
- Confirm that the calculator title and method match the quantity, test, conversion, or planning question you need to solve.
- Enter values with compatible units and the requested sample, group, matrix, count, date, or option format.
- Select Example Data to inspect a valid input layout, or enter your own values and select Calculate.
- Review the result table, formula, worked substitutions, warnings, and interpretation rather than using only the headline number.
- Use Copy Result or Download CSV when you need a reusable record of the displayed calculation.
Understanding the Result
Use one consistent unit system and verify field measurements, tolerances, openings, waste factors, and local construction requirements.
Keep the entered values, units, selected options, and any warning shown beside the result. For a hypothesis test, report the statistic, degrees of freedom where applicable, p-value, alpha level, effect size, and decision. For an estimate or conversion, report the formula convention and final unit.
Accuracy and Limitations
The calculator keeps full browser precision during calculation and rounds only for display. Accuracy still depends on correct inputs and on whether the displayed model represents the real problem. Educational calculators cannot replace required professional review, current official rules, field measurements, laboratory methods, or specialist statistical software where those are necessary.
Frequently Asked Questions
