An Olympic-size swimming pool holds over 2 acre-feet of water For larger volumes of liquid, one measure commonly used in the media in many countries is the Olympic-size swimming pool. [47] A 50 m × 25 m (164 ft × 82 ft) Olympic swimming pool, built to the FR3 minimum depth of 2 metres (6.6 ft) would hold 2,500 m 3 (660,000 US gal).

The standard brick sizes in Mesopotamia followed a general rule: the width of the dried or burned brick would be twice its thickness, and its length would be double its width. [ 8 ] The South Asian inhabitants of Mehrgarh also constructed air-dried mudbrick structures between 7000 and 3300 BC [ 9 ] and later the ancient Indus Valley cities of ...
[59] [60] Masonry drill bits and standard expandable wall plugs are not suitable for use with AAC blocks. [60] Using European standard density (400 kg/m 3, B2,5), AAC blocks alone would require very thick — 500mm or thicker — walls to achieve the insulation levels required by newer building codes in Northern Europe. [57]
the medium gross density of 850 kg/m 3 to 1.100 kg/m 3 (white coloured blocks, suitable for standard usage) the high gross density blocks of 1.100 kg/m 3 to 1.500 kg/m 3 (reddish colour, suitable for walls with higher acoustic performance requirements) The dimensions of these blocks are: length 500 mm, height 500 mm. Four blocks thus make 1 m 2.
The blocks vary in size but are often 2 m × 0.75 m × 0.75 m (6.6 ft × 2.5 ft × 2.5 ft). The primary function of geofoam is to provide a lightweight void fill below a highway, bridge approach, embankment or parking lot.
