Working dimensions is the size of a manufactured brick. It is also called the nominal size of a brick. Brick size may be slightly different due to shrinkage or distortion due to firing, etc. An example of a co-ordinating metric commonly used for bricks in the UK is as follows: [4] [5] [6] Bricks of dimensions 215 mm × 102.5 mm × 65 mm; Mortar ...
One acre equals 1 ⁄ 640 (0.0015625) square mile, 4,840 square yards, 43,560 square feet, [2] or about 4,047 square metres (0.4047 hectares) (see below).While all modern variants of the acre contain 4,840 square yards, there are alternative definitions of a yard, so the exact size of an acre depends upon the particular yard on which it is based.
These structures were made up of the first bricks with dimension 400x150x100 mm. [7] Between 5000 and 4500 BC, Mesopotamia had discovered fired brick. [7] 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 rod, perch, or pole (sometimes also lug) is a surveyor's tool [1] and unit of length of various historical definitions. In British imperial and US customary units, it is defined as 16 + 1 ⁄ 2 feet, equal to exactly 1 ⁄ 320 of a mile, or 5 + 1 ⁄ 2 yards (a quarter of a surveyor's chain), and is exactly 5.0292 meters.
The existence of section lines made property descriptions far more straightforward than the old metes and bounds system. The establishment of standard east-west and north-south lines ("township" and "range lines") meant that deeds could be written without regard to temporary terrain features such as trees, piles of rocks, fences, and the like, and be worded in the style such as "Lying and ...
The use of brick construction increased in Chicago after the Great Chicago fire of 1871. They are called common brick since they were used in multiwythe mass walls with many of the brick used on inner wythes while a facing brick was used for the outer wythe. Most of the brick manufacturers closed around the middle of the 20th century, and now ...
If the railway ran predominantly north and south, a 10-mile (16 km) township of one square mile sections was allotted on each side of the 400-foot (120 m) right-of-way. The land was granted in alternating sections (one square mile), with each odd numbered section going to the railroad company and each even numbered section kept by the government.
The agricultural foot was reduced to 10 ⁄ 11 of its former size, causing the rod, pole or perch to become 16 + 1 ⁄ 2 (rather than the older 15) agricultural feet. The furlong and the acre , once it became a measure of the size of a piece of land rather than its value, remained relatively unchanged.
