Size in Gal?

[Angryeric116]

Hi i used to be a regular a long time ago, but i haven't been on this forum in a long time...
I recently purchased a plastic tank at a garage sale for just five bucks! i have already leak tested it and it seems to be good. I think it is around 50 us gallons but i do not know.
I was just wondering if anyone could tell me the capacity (in us gal) for this tank?
the dimensions are 48"L x 13"W x 20" H

Plastic? You can't use heaters in plastic aquariums, can you?

Yeah, I think it's a 55. Here's a handy chart. Quick Calculator for Aquariums Theres a formula too, it's width x height x depth /231.

Using inches:

(in any order) height times length times width divided by 231 equals gallons.
