How to Calculate Rectangular Tank Volume

Compute the volume of a rectangular tank, box, or container using length × width × height. Results in mL, liters, and cubic meters.

Example: a water tank 1.5 m long, 1 m wide, and 0.8 m tall holds 1,200 liters. An aquarium 60×30×40 cm holds 72 liters.

Also calculates partial fill volume when the tank is not completely full. Enter fill height to see current volume.
