Geometry Area & Volume Calculator
Calculate area for 2D shapes, or volume and surface area for 3D shapes.
Assumptions used in this calculation
- Unit consistency: All dimensions for a given shape must be entered in the same unit; the calculator does not perform unit conversion.
About this calculator
Calculates area for common 2D shapes (square, rectangle, triangle, trapezoid) and volume plus surface area for 3D shapes (cube, cuboid, cylinder, sphere, cone), consolidating the master prompt's separate 'Geometry Area Calculator', 'Geometry Volume Calculator', and 'Surface Area Calculator' into one shape-selector tool.
Worked example
Cube with 3-unit sides
Result: Volume = 27, surface area = 54
