Calculate the volume of one brick:

`Volume of one brick = Length × Width × Height = 0.19m × 0.09m × 0.09m = 0.001539 cubic meters`

Now, calculate the total volume of bricks needed:

`Total volume of bricks = Area × Number of bricks per square meter`

Assume there are 500 bricks per cubic meter:

`Total volume of bricks = 30 square meters × 500 bricks = 15,000 bricks`

Next, calculate the volume of mortar required. Assume the mortar thickness is 10mm or 0.01 meters. Use the following table for better understanding:

Component | Volume Calculation |
---|---|

Mortar thickness | 0.01 meters |

Volume of mortar | Area × Thickness = 30 sqm × 0.01m = 0.3 cubic meters |

Finally, combine the volumes of bricks and mortar to get the total volume:

`Total volume = Volume of bricks + Volume of mortar = 15,000 bricks + 0.3 cubic meters`

With these calculations, you can accurately determine the amount of cement needed for your brickwork.

For example, if you need 100 bags of cement, add 5 more bags for wastage. This ensures you have enough material to complete the job.

Here is a simple formula to account for wastage:

```
Total Cement = Calculated Cement + (Calculated Cement
```** Wastage Percentage)
**

Let’s say you calculated you need 100 bags of cement. With a 5% wastage, you will need:

```
Total Cement = 100 + (100
```** 0.05) = 105 bags
**
