Oh, oh! A Calculation...
Hmmm... considering a block of C4 looks to be about the same size as a brick, we're talking about 4x3x8 per 1-lb block. You can thus pack about 3 wide by 4 high for 12 blocks plus another 4.5 along the narrow edge. That's about 16.5 lbs per cubic foot.
A standard room measures about 10x10 ft square with an 8-ft ceiling. That gives us 800 cubic feet.
Packing the room full of C4 gives you 800x16.5=13,200 lbs of C4.
That'll make one helluva' BIG BOOM!
