How to Calculate Volume

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains.

Rectangular Tank / Box

Volume = Length × Width × Height

Standard for concrete slabs, aquariums, and shipping boxes.

Cylinder

Volume = π × r² × Height

Used for concrete columns, round water tanks, and pipes.

Cone

Volume = (1/3) × π × r² × Height

Used for conical piles of sand, gravel, or soil.

Practical Applications

This calculator is essential for construction estimating. Use it to calculate the amount of concrete needed for footings, the capacity of a water tank, or the volume of soil required for a raised garden bed. Remember that volume is measured in cubic units (ft³, m³, yd³).
