The calculation, explained.
A rectangular volume is length × width × height. Cylinder volume is π × radius² × cylinder height. In cylinder mode, the height/radius field is a radius, not a diameter; width is not used.

How this tool works
Adjust the labeled inputs to see a new calculation. Units and assumptions are shown beside each field. Printed and copied results use the same calculation.
This is a planning estimate, not a structural design, permit document or binding quote. Check product specifications and actual site measurements.
