Surface Area Calculators – Geometry & 3D Shape Tools

Instantly determine surface area for common 3D shapes using our surface area calculators. Great for geometry, school assignments, engineering, design, and construction planning.

Surface Area Calculator Toolbox

Rectangular Tank Surface

Calculate surface area of any tank or box (l × w × h)—real-world and homework uses.

Cube Surface Area

Find area for classic cubes (6 × side²). Easy, clear explanation.

Sphere Surface Area

4πr² made simple—perfect for spheres of any size or material.

Cylinder Surface Area

Area for closed or open cylinders by radius and height—good for sciences and engineering.

Capsule Surface Area

Find the area of a pill/capsule (cylinder + hemispherical ends). Used in pharmacy & design.

Spherical Cap Surface Area

Calculate the curved surface of a sphere segment/cap—handy in STEM.

Conical Frustum Surface Area

For truncated cones—find side & total area for any base/radius combo.

Ellipsoid Surface Area

Areas for football/egg-shaped solids—multi-axis calculation, accurate output.

Cone Surface Area

For right cones—base, lateral, and total area, with diagrams and steps.

Square Pyramid Surface Area

Area of faces & base with edge/slant height—useful in math and building design.

Tube Surface Area

Surface of hollow tubes (pipes)—outer, inner, or total for real-world engineering.
