Learn the mathematical formulas behind tank volume calculations
Formula: V = π × r² × h
Most common for water storage, fuel tanks, and industrial applications.
Formula: V = l × w × h
Perfect for custom-built tanks and space-efficient storage solutions.
Formula: V = (4/3) × π × r³
Ideal for high-pressure storage and maximum volume with minimal surface area.
How a family in Mumbai calculated their optimal water storage capacity
The Sharma family needed to install a water storage tank for their 4-member household. With irregular water supply, they wanted 3 days of backup storage.
Using our calculator, they determined a cylindrical tank with 1.2m radius and 2.1m height would provide exactly 2,900 liters - perfect for their needs!
