Explanation:

To calculate the total quantity of brickwork, we need to find the volume of the wall. The volume is calculated by multiplying the length, width, and height of the wall.

Given:

  • Length = 7 m

  • Width = 0.3 m

  • Height = 3 m

Formula

Volume = Length × Width × Height

Substitute the values:
Volume = 7 m × 0.3 m × 3 m = 6.3 m³

So, the total quantity of brickwork required is 6.3 m³.
