4.5 inch wall BRICK CALCULATIONS
BRICK CALCULATIONS for 4.5 inch wall
suppose, we have
Brick Size = 9” x 4.5” x 4.5”
Thickness of Wall = 4.5”
Thickness of Mortar = 0.4”
Height of wall = 6'
Length of wall=
= 10'
= (9+0.4) x
(4.5+0.4) x (4.5+0.4)
=
9.4 x 4.9 x 4.9
Now,
Number of bricks = Volume of Brickwork / Volume of 1 brick with mortar
Also, volume of 1 Brick
= 9 x 4.5 x 4.5
=
182.25 cubic inch
We know 1 feet = 12 inches
Therefore,
Volume of 1 brick (feet)
= 182.25 / (12 * 12 *12)
= 0.055 cubic feet
Also,
Volume of 1 brick with mortar
= 9.4 x 4.9 x 4.9
= 225.694
cubic inch
(In feet) = 225.694 / (12 * 12 *12)
Volume of 1 brick with mortar = 0.131 cubic
feet
Now,
Volume of Brick
=
(Height x length x Width) of wall
= 10 x 6 x 9/12
= 45 cubic feet
Therefore,
Number of
bricks = Volume of Brickwork / ( Volume of 1 brick with mortar)
= 45 / 0.131
= 344 bricks
Also,
There will wastage of brick,
Let it consider to be = 10 % of brick wastage
