in face we calculate around 60 bricks.. but behind the wall there are double bricks in of footer brick... so calculate the footer brick as a double...
The square pyramidal's bond angkle is 95 degrees hgjhgyuthvjyy,kufgy
The molecular geometry is square planar and the bond angle is 90 degrees
It is square planar, please see related link. (bond angle Kr-F is 90 degrees)
First, find the square footage of an 8" x 8" tile. 8 x 8 = 64 square inches. There are 144 square inches in a square foot (12" x 12" = 144). So divide 64 by 144 to get the square feet per tile. 64 / 144 = 0.44 sq ft per tile. You have 176 square feet, using tiles that are 0.44 sq ft each. 176 / 0.44 = 400 tiles. Generally, you will want to add from 5% to 10% for waste, depending on your layout (is it one big area, or several smaller areas with lots of cutting?) (are you doing a checkerboard pattern, running bond (brick), or diagonal?) and your skill level. If in doubt, add 10% to be safe. 400 tiles + 10% --- that's 400 x 1.1 = 440 tiles.
First, find the square footage of an 18" x 18" tile. 18 x 18 = 324 square inches. There are 144 square inches in a square foot (12" x 12" = 144). So divide 324 by 144 to get the square feet per tile. 324 / 144 = 2.25 sq ft per tile. You have 1800 square feet, using tiles that are 2.25 sq ft each. 1800 / 2.25 = 800 tiles. Generally, you will want to add from 5% to 10% for waste, depending on your layout (is it one big room, or several smaller rooms with lots of cutting?) (are you doing a checkerboard pattern, running bond (brick), or diagonal?) and your skill level. If in doubt, add 10% to be safe. 800 tiles + 10% --- that's 800 x 1.1 = 880 tiles.
English bond use a lot of facing brick, but it stability is higher than stretches bond.
The three types of brick bonding are,English bondFlemish bondStretcher bond
Header,english,stretcher and others
In English bond, bricks are laid in alternating courses of stretchers and headers. One layer will show the sides (stretchers) of the bricks, while the next layer will show the ends (headers) of the bricks. This pattern is repeated throughout the courses using English bond brick laying.
90. (60 stretchers and 30 headers)
Masonry bond refers to the pattern of the bricks within a wall. The most basic is running bond, where all brick within a wall are stretchers (laid with the long, narrow face outward). In English bond, a course of stretchers is followed by a course of header brick, which are laid with their longer edge going back into the wall. This gives the wall a horizontal striped pattern. In Flemish bond, adjacent bricks in each course alternate between stretcher and header, and the next course is reversed. This gives the wall a diagonally striped pattern. I'm less certain of this next (because these bond patterns are expensive and rarely used in brick veneer construction), but I believe single vs double Flemish bond refers to the thickness of the wall. Single is actually two wythes of brick (an inside and an outside wythe) where double is three or more wythes thick. This allows the pattern on the inside to be more independent of the outside pattern, and simplifies corners and masonry openings.
English bond refers to a type of brickwork bond used in the construction of (usually) load-bearing walls. Brick homes commonly built in the US today use a type of brickwork called a stretcher bond. Basically, a stretcher bond is a single row of bricks (about 4" thick - called a half-wythe) laid longwise end-to-end (stretchers). This type of construction is really just a brick veneer which is supported by load-bearing wall elements behind it - such as 2x4 wood frame construction, "cinder block", or a poured concrete wall. A brick wall employing a English bond, on the other hand, is a full wythe thick (about 8" - the length of a standard brick). It's made by alternately laying a row of two bricks "longwise" side-by-side (stretchers) and then a row of bricks "crosswise" (headers). The joints are staggered so that the header bricks (and mortar) lock in the stetcher bricks in the rows above and below them and, likewise, the stretcher bricks (and mortar) lock in the header bricks in the rows above and below them.
A king closure is a brick cut to bond in a corner of brickwork, a brick with a corner cut off.
So a network covalent bond or macromolecular bond is basically a bunch of covalently bonded atoms. Imagine a diamond structure or crystal structure that keeps expanding but a model only shows a building block of the substance. So like a brick wall to a brick.

Flemish bond wall construction is not as strong as the English bond brick wall.In a Flemish Bond wall, alternate header and stretcher are laid in every course of the bricks, header bricks being centrally placed between the stretcher bricks in a course and between the stretchers of the top and bottom courses.See the pic in related link for the intersection in Flemish Bond wall construction.
In case of the English bond bricks were laid in alternate layers of headers and stretchers. while flemish bond has alternate headers and stretchers within a layer, giving good looks to the surface. English bond has high strength value while flemish bond has looks.
