The number of bricks in 1 cubic meter varies based on the size of the bricks and the presence and thickness of mortar. However, as per general estimate, the number of bricks with mortar in 1 cubic meter would be approximately 500 bricks and without mortar would be about 650 bricks.

The number of bricks depends on the dimensions of the bricks. Assuming the actual size of the brick without mortar includes (Length x Width x Height) :190mm x 90mm x 90mm. The thickness of the mortar joints is approx. 10 mm. Together with the mortar joints, this results in a nominal brick size of 200 mm x 100 mm x 100 mm.

To calculate the volume of one brick without mortar, multiply the dimensions together: 0.19 m x 0.09 m x 0.09 m = 0.001539 cubic meters per brick. To find the number of bricks in 1 cubic meter without mortar, divide 1 by the volume of one brick: 1 / 0.001539 ≈ 650 bricks.

To calculate the volume of one brick with mortar, multiply the dimensions together: 0.2 m x 0.1 m x 0.1 m = 0.002 cubic meters per brick. To find the number of bricks in 1 cubic meter with mortar, divide 1 by the volume of one brick: 1 / 0.002 ≈ 500 bricks.

The number of bricks will be slightly less when mortar is included because mortar occupies space between bricks. The amount of mortar used can vary based on the type of bricklaying technique and the thickness of mortar joints.

**Here’s are general estimate for how many bricks in 1 cubic meter with and without mortar:-**

- The number of bricks with mortar in 1 cubic meter would be approximately 500 bricks. The number of bricks in 1 cubic meter with mortar: 1 / 0.002 ≈ 500 bricks.
- The number of bricks without mortar in 1 cubic meter would be approximately 650 bricks. The number of bricks in 1 cubic meter without mortar: 1 / 0.001539 ≈ 650 bricks.

Conclusions:-

As per general estimate, the number of bricks with mortar in 1 cubic meter would be approximately 500 bricks and without mortar would be approximately 650 bricks.
