Volume Calculator
Calculate the volume of common 3D shapes for construction projects, material estimation, and engineering. This calculator supports rectangular boxes (cubes), spheres, cylinders, and cones, with results in multiple units including cubic feet, cubic meters, cubic yards, gallons, and liters.
Volume formulas used:
- Rectangular Box: V = length × width × height
- Sphere: V = (4/3)πr³
- Cylinder: V = πr²h
- Cone: V = (1/3)πr²h
Unit conversions:
- 1 cubic foot = 0.02832 cubic meters
- 1 cubic yard = 27 cubic feet
- 1 cubic foot = 7.481 US gallons
- 1 cubic foot = 28.317 liters
Construction applications: The rectangular box formula covers room volumes (for HVAC sizing), soil fill, and material storage. Cylinder volumes are needed for tanks, pipes, and columns. Cone volumes apply to piles of gravel, sand, and similar materials.
