The number of bricks required for a 10×10 or 100 sq ft room depends on the thickness of the wall and the size of the bricks. Because the thickness of the wall can be 4.5 inches or 9 inches. Therefore More bricks are required in a 9-inch thick brick wall. While a wall of 4.5 requires fewer bricks than a wall of 9 inches. That’s why in this article we will calculate how many bricks required for 10×10 (100 sq ft) 4.5 and 9-inch brick wall.
As I have already told you the number of bricks in 100 sq ft brick wall also depends on the size of the bricks. So you should have to know what size brick you have. In this article, I will use 9″× 4.5″× 2.5″ size brick. According to your brick size, and thickness of mortar your estimation for the number of bricks can be different.
Required bricks for 10×10 (100 sq ft) 4.5 and 9-inch thick Brick Wall
To calculate the number of bricks in a brick wall. We have to know the thickness of the brick wall and the dimensions of the brick wall. Once we find the brick wall thickness and the dimensions of the brick wall. Then first we have to find the volume of a brick with mortar thickness. After that find the volume of the brick wall. Then divide in the volume of a brick wall by the volume of a brick.
Number of bricks required for 10×10 (100 sq ft) 4.5-inch brick wall
Cement mortar needs to construct a brick wall. So we have added mortar thickness in brick size. Generally, mortar thickness is considered 0.5 inches in the construction of the brick wall.
Normal brick size = 9 × 4.5 × 2.5 inches.
In this dimension 9 inches is the length of the brick, 4.5 inches is the width of the brick and 2.5 inches is the thickness of the brick.
Now we will add mortar thickness in normal brick size. But will not add mortar thickness to the width of the brick. Because in the thickness of 4.5 inches brick wall mortar has not been used in width.
Brick size with mortar thickness = (9 + 0.5) × (4.5) × (2.5 + 0.5)
= 9.5 × 4.5 × 3
Now we will find the volume of a brick with mortar thickness
so, Volume of 1 brick with mortar = length × width × thickness
= 9.5/12 × 4.5/12 × 3/12
We are dividing by 12 in each dimension. Because we want volume in a cubic foot, and in 1 foot there are 12 inches.
= 0.791 × 0.375 × 0.25 = 0.074 cubic foot.
So the volume of 1 brick is 0.074 cubic feet.
Now we will calculate the volume of the brick wall
So, the Height of the brick wall = 10 feet.
Width of brick wall = 10 feet.
The thickness of the brick wall = 4.5 inches.
The volume of the brick wall = Height × width × thickness.
= 10 × 10 × 4.5/12
= 37.5 cubic feet.
Now the number of bricks needed for 10×10 4.5 inches brick wall = volume of brick wall ÷ volume of 1 brick
= 37.5 ÷ 0.074 = 506.75 = 507 bricks.
There are 507 bricks required for a 10×10 (100 sq ft) 4.5-inch thick brick wall. If you take brick size 9″× 4.5″× 2.5″.
Number of bricks required for 10×10 (100 sq ft) 9-inch brick wall
Cement mortar needs to construct a brick wall. So we have added mortar thickness in brick size. Generally, mortar thickness is considered 0.5 inches in the construction of the brick wall.
Normal brick size = 9 × 4.5 × 2.5 inches.
In this dimension 9 inches is the length of the brick, 4.5 inches is the width of the brick and 2.5 inches is the thickness of the brick.
Now we will add mortar thickness in normal brick size. But will not add mortar thickness to the width of the brick.
Brick size with mortar thickness = (9 + 0.5) × (4.5 + 0.5) × (2.5 + 0.5)
= 9.5 × 5 × 3
Now we will find the volume of a brick with mortar thickness
So, the Volume of 1 brick with mortar = length × width × thickness
= (9.5/12) × (5/12) × (3/12)
We are dividing by 12 in each dimension. Because we want volume in a cubic foot, and in 1 foot there are 12 inches.
= 0.791 × 0.416 × 0.25 = 0.074 cubic foot.
So the volume of 1 brick with mortar is 0.082 cubic feet.
Now we will calculate the volume of the brick wall
So, the Height of the brick wall = 10 feet.
Width of brick wall = 10 feet.
The thickness of the brick wall = 9 inches.
The volume of the brick wall = Height × width × thickness.
= 10 × 10 × 9/12
= 75 cubic feet.
Now the number of bricks needed for 10 ×10 9 inches brick wall = volume of brick wall ÷ volume of 1 brick
= 75 ÷ 0.082 = 914.63 = 915 bricks.
There are 915 bricks required for a 10×10 (100 sq ft) 9-inch thick brick wall. If you take brick size 9″× 4.5″× 2.5″.
Conclusion
Guys In this article we have calculated the required number of bricks for 100 sq ft brick wall. We require the 915 bricks needed for a 10×10 9-inch thick brick wall and 507 bricks needed for a 10×10 4.5-inch thick brick wall. But These number of bricks can differ according to your brick size and mortar thickness. But don’t worry you can calculate the actual number of bricks using the above method which I have told you.
