Calculate the volume of 3D shapes with formulas, surface area, and material estimates
Volume measures the amount of three-dimensional space occupied by an object, expressed in cubic units. It quantifies capacity, displacement, and spatial occupancy.
Volume calculations are essential in engineering, construction, shipping, liquid storage, material estimation, and manufacturing. They determine capacity, costs, and resource requirements.
Polyhedra (flat faces), curved solids (spheres, cylinders), composite shapes, and irregular forms each require specific formulas and calculation methods.
Calculations assume perfect geometric shapes. Real objects may have irregularities, hollow sections, or varying densities. Complex shapes may require integration or approximation.
Volume is fundamental in geometry, physics, and calculus education. This calculator supports homework, laboratory work, and conceptual understanding of 3D space.
Used in architecture for space planning, engineering for material volumes, shipping for container capacity, chemistry for solutions, and manufacturing for production.

Archimedes discovered volume displacement principles over 2,200 years ago in ancient Greece
Understanding volume is critical for 91% of STEM careers and technical professions
Cube the linear conversion factor. For example, 1 meter = 100 cm, so 1 m³ = 1,000,000 cm³. For imperial units, 1 ft³ = 1,728 in³, and 1 yd³ = 27 ft³.
Volume measures the space inside a 3D object (cubic units), while surface area measures the total area of all external faces (square units). A box has volume inside and surface area outside.
For irregular shapes, use water displacement method physically, or decompose into regular shapes mathematically. Complex shapes may require calculus integration or 3D scanning technology.
Determining tank capacity, calculating concrete for construction, shipping container optimization, medication dosing, fuel tank design, and swimming pool water requirements.
Volume formulas come from integration in calculus, geometric principles, or empirical methods. The cube (l×w×h) is fundamental, with other shapes derived through mathematical proofs.
Weight = Volume × Density. The same volume of different materials weighs differently based on density. Water is 1000 kg/m³, steel is 7850 kg/m³, and air is 1.225 kg/m³.
Use the shape of the container. Common conversions: 1 liter = 1000 cm³, 1 gallon = 3.785 liters. For partial fills, calculate the filled portion's geometry.
