I have seen two numbers for coal density
40 ft3/ton (rule of thumb for coal bunkers) (801 kg/m3)
833 kg/m3 (bituminous, broken) (38.5 ft3/ton)
You need to decide what depth you want to fill it to, then figure square footage based on the required volume:
A = 40 ft3/(depth in feet)
For any given depth of container, a square container will require the least area in the sides of the container. A cubical bin for a ton of coal made using the rule of thumb would be about 41 inches on each edge. Be mindful of the weight and the corresponding structural requirements.
