Skill: area-volume
Area and Volume Calculator
Three tools in one: area of 2D shapes, volume of 3D solids, and a missing-dimension solver.
Every answer comes with the full working shown step by step.
Area of a 2D shape
Pick a shape, enter its dimensions. The calculator shows each step.
Area answers need square units (cm², in², ft²).
Volume of a 3D solid
Pick a solid, enter its dimensions. The calculator shows each step.
Volume answers need cubic units (cm³, in³, ft³).
Find a missing dimension
Know the area or volume but not one side? Enter what you know and solve backwards.
