The xiphoid process is the smallest and most inferior region of the sternum, or breastbone. At birth, it is a thin, roughly triangular region of cartilage that slowly ossifies into a bone and fuses with the body of the sternum.
City Blocks differ in size, but the typical square city block reaches 16 or 17 per mile, or 2.21 to 2.50 Acres. Engineers use a typical city block as 100,000 sq. ft. for calculation estimates, which is about 17 blocks per mile or 2 1/4 acres. (A football field is 300 feet by 160 feet, which is 1.1 Acres.)
For example, in Melton-East, Melbourne, the average block size of a new house has fallen from 716sqm in 1994-95 to 571sqm in 2003-04; the average block size of a new house in Bankstown, Sydney, has fallen from 667sqm in 1998-99 to 614sqm in 2003-04. A minority of SLA's have bucked the trend.ence over the last four years the average site area has ticked up moderately, but looks to have stabilised at around the 735sqm mark, still some 67sqm smaller than 11 years previously.
