Ggans, try to find grain bags if you want to bag your own coal. Breweries and feed stores have lots of them. They're a heavy woven plastic, usually 70-80lb when full of grain. I've filled them full of coal and not had one break.

48" x 48" x 48"=110592 cubic inches divide that by 12 cubed(1728)=64 cubic feet
coal is 50 pounds/cubic feet , so (50 pounds/cubic feet) x (64 cubic feet)= 3200 pounds
minus the volume of 11 2x4's=150 pounds, so 3200-150=3050 pounds if filled completely.
I put the 2x4's on the inside of the bin and the bin looses 150 pounds as compared to
putting the sheathing on the inside, the bin looses 700 pounds. A difference of 500 pounds..
This bin cost $65.00 , home depot , 3 sheets 1/2" usb, I did put a top and door on it, (11) 2x4's, 3" screws and 2" screws.
The coal was free for the loading, 2 loads = 2 tons, so I built 2 of these, one for home and
one for shop, no more carrying one building to another,

The easy way to do math for those like me who never got into mathimagican school .. 4'x4'x4' = 64 divide by 40 = 1.6 ton or 3200 #

For pea I've simplified it down to 1.3 cubic yards = 1 ton
