Compute volume, surface area, and lateral area for prisms, pyramids, frustums, cylinders, cones, and spheres—with step-by-step formulas.
Assumption
Right / Regular formulas
All inputs are treated as consistent units (e.g., cm). Areas then follow automatically.
Tip
For a right prism, lateral area is P_base · h.
Select a solid, enter parameters, then click Calculate.
