🧮 How to calculate the cost of clay bricks? (Includes calculation formula)

The basic formulas used by the program: Quantity of bricks = Net area × Number of bricks per sq.m. × Waste margin

Example calculation:

  • Wall area 50 sq.m.
  • Use standard clay bricks conforming to Thai Industrial Standard 77-2565 (120 bricks/sq.m.)
  • In case of damage, 10%
  • Way of thinking: 50 × 120 × 1.10 = 6,600 pieces
