<HTML>Yup. 125 per cubic foot.
EXTREMELY brittle. My secretary broke a piece into 3 pieces -- 1 inch thick -- with her bare hands.
The dramatically light weight (125/cu.ft) is because it is highly porous, and riddled with little airbubbles all the way through.
I would give the dimensions of the biggest block as approx. 3 feet thick, 12 feet high, 12 feet wide.
This is a MONSTROUS block, with a hole drilled right through the middle... it's solid.
Each of the outer wall blocks (67 in total) are approximately 2 feet thick, 8 feet high, and 5 feet wide.
Some of the smaller block are found in his living quarters. I would say they are aboug 6' x 4' x 1.5'.
I hope this helps.
