Coal Bin Size

I want to build a coal bin to hold 6 ton of rice coal, how big should it be? Length, width,height.

Approximately 40 cubic fett per ton, it's not exact and making room for a extra ton or so is always advisable unless your building outside and you'll have complete access to it. 8x8x4 will fit apporoximately 6.4 tons.
