4 foot aquarium query?

I saw a 4 foot aquarium but i forgot to ask how many gallons/litres there are in it.
Could anyone describe me the possible capacity of it(its a regular rectangular one)

It's likely to be 55 or 75 gal depending on the other measurements. Thats the common sizes anyway, but you can return with oddball size tanks that are custom made and could be bigger or smaller capacity.

All of the following tanks are rectangular, and are 48 inches long. It could be a:

33 long

40 long

55

75

90

105

110 additional high

120 high

150 extra dignified

I really can't tell you the exact gallon size until I know the width (front to back), and the height of the cistern.
