IF a tank were filled to 100% of capacity, then increases in temperature would result in pressure increases on the tank of hundreds, or possibly thousands, of PSI, and possibly cause a very severe mechanical failure resulting in a massive fire and/or chemical explosion.
This is because liquids have very little compressability, while gasses like air, or LPG in gasseous form, are very highly compressable.
Safety codes require that some empty space remain above the liquid after "filling" of a tank. Then moderate pressure increases due to moderate temperature increases are safely absorbed, or buffered, allowing only moderate pressure increases to the tank.
As pointed out in answer 1, it is theoretically possible of phically and totally fill a tank, but if proper safety valving and filling techniques are used, then there will always be a "headspace" for safety in the tank at all times.
23.6 gallons. That's the volume of 100 lbs of propane, however, they only fill to about 80% (to allow room for expansion with temperature; otherwise you'd blow out liquid propane!).
A 100 pound propane tank has a capacity of 2,160,509 BTUs

Around $75 it's usually $15 for the 20lb tanks.

100 pound propane tank will hold 23.58 gallon. 100 pounds / 4.24 pounds per gallon = 23.58 gallons
The blast radius of a 250 gallon propane tank would be 100 yards

260 pounds for the tank plus about 400 pounds of propane. 660 pounds total.
100 gallons? Are you kidding me. Who asked this question. You need not be dealing with propane. Believe it or not, there are 1000 US Gallons in a 1000 "Gallon" propane tank. Some peoples kids.
