Three dimensions are required to calculate the volume (width, height, length). You provided only two.
To calculate how many gallons it holds you first multiply the three dimensions together (5*6*?). You'll get the volume of your barrel in cubic feet. Then you can use our
volume conversion page to convert it from cubic feet to gallons.
