Stacking layers
Many volume formulas multiply the area of a base by height, like stacking equal layers upward.

Choose a 3D shape, enter its measurements, and see the volume formula, diagram, cubic units, and step-by-step solution.
Input fields change automatically for the selected shape.
Switch shapes to practice common school geometry formulas without opening a separate calculator each time.
Many volume formulas multiply the area of a base by height, like stacking equal layers upward.
A volume of 125 cm³ means the shape takes up the same space as 125 tiny cubes that are 1 cm on each side.
Cylinders, cones, and spheres use pi because circles are part of their geometry.
