**Quantity of bricks depends upon the following parameters:**

1.Size of Bricks

2.Thickness of wall

•Full or 1 brick thick wall

•Half brick thick wall (Partition wall)

3.Thickness of mortar

### CASE 1:

Assumptions:-

Size of Brick—>8”x4”x4”

Thickness of mortar = 0.4″

Thickness of wall = 9”

**No. of bricks = Volume of brickwork/ volume of 1 brick with mortar**

*Volume of 1 Brick with mortar = 8.4”x4.4”x4.4” =162.624 inch^3.*

*Volume of brickwork = Thickness of wall x Area of brickwork*

*Volume of brickwork = 9”x 144”=1296 inch^3* (∵1sq.ft=144”)

*No. of bricks = 1296/162.624 = 7.969 ≊ 8 No’s* (without considering percentage of wastage)

**Consider the wastage percentage as 10 %**

Then,

No. of bricks with wastage = 8+0.8=8.8 No’s

If**, THICKNESS OF WALL = 4.5”**

Then,

No. of bricks **without wastage = 4 No’s**

No. of bricks** with wastage= 4.4 No’s**

### CASE 2:

Assumptions:-

Size —> 9”x4.5”x3”

Thickness of mortar = 0.4″

Thickness of wall = 9”

**No. of bricks = Volume of brickwork/ volume of 1 brick with mortar**

Volume of 1 Brick with mortar = 9.4”x4.9”x3.4” = 156.604 inch^3.

Volume of brickwork = 9”x 144”=1296 inch^3 (∵1sq.ft=144”)

No. of bricks in 1sq.ft = 1296/156.604 = 8.27 ≊ 8.3 No’s (without considering percentage of wastage)

**Consider the wastage percentage as 10 %**

Then,

No. of bricks **with wastage = 8.27+0.827=9.10 No’s**

If, **THICKNESS OF WALL = 4.5”**

Then,

No. of bricks** without wastage** **= 4.14 No’s**

No. of bricks** with wastage = 4.55 No’s**
