Surface Area Calculator

The Surface Area Calculator accurately computes surface areas for 5 major 3D shapes: spheres, cylinders, cones, cubes, and rectangular prisms. No need to memorize complex formulas - just enter the required dimensions and get instant results. Useful for math learning, scientific experiments, architectural design, and product design.

Uses precise mathematical formulas for each shape. For spheres: 4πr², cylinders: 2πr(r+h), cones: πr(r+√(r²+h²)), cubes: 6a², and rectangular prisms: 2(lw+lh+wh). All calculations are performed with high precision, and results are displayed accurately to decimal places.

Results are displayed not only numerically but also as visual charts. Using Chart.js graphs, you can intuitively understand the relationship between input dimensions and calculated surface area. Useful for educational materials and presentation preparation.

Surface area is crucial when calculating material requirements in architectural design or product design. Accurately calculate paint coverage area, packaging material needs, insulation size, and more. Helps predict material costs and reduce waste in real projects.

An excellent educational tool for students to understand 3D shape surface area concepts. Learn formula applications by entering values and checking results. Experiment with different values to observe how surface area changes with dimension changes, helping develop mathematical thinking skills.

Responsive design makes it convenient to use on smartphones, tablets, PCs, and all devices. Calculate surface areas anytime, anywhere with just a web browser - no app installation required. Supports dark mode for comfortable use at night without eye strain.
