Understanding Tank Volume Formulas
Learn the mathematical formulas behind tank volume calculations
Cylindrical Tanks
Formula: V = π × r² × h
Most common for water storage, fuel tanks, and industrial applications.
Rectangular Tanks
Formula: V = l × w × h
Perfect for custom-built tanks and space-efficient storage solutions.
Spherical Tanks
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 Challenge
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.
Calculation Process:
- Daily water usage: 200 liters per person × 4 = 800 liters
- 3-day storage needed: 800 × 3 = 2,400 liters
- Added 20% buffer: 2,400 × 1.2 = 2,880 liters
Solution Found:
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!
