How many liters of water are in your tank 2ft long and 1ft high and 1ft wide and a half feet high?

The problem is to convert cubic feet to liters.

Starting with 1 cu ft = 28.3168 liters

2 ft x 1 ft x 1 ft tank volume = 2 cu ft capacity

If tank is only half full that would be 1 cu ft of water which = 28.3168 liters
