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).
