1. What is a Paving Brick Calculator for South Africa?

Definition: This calculator estimates the number of paving bricks needed based on the area to be paved and the area covered by each brick.

Purpose: It helps homeowners and contractors accurately plan paving projects and purchase the correct quantity of bricks.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( N \) — Number of bricks needed
• \( A \) — Total area to be paved (square meters)
• \( Ab \) — Area covered by one brick (square meters)

Explanation: The total area is divided by the area covered by one brick to determine the quantity needed.

3. Importance of Accurate Brick Calculation

Details: Proper calculation prevents material shortages or excess, ensures cost efficiency, and helps with project planning.

4. Using the Calculator

Tips: Enter the area to be paved in square meters and the area covered by one brick (default 0.01 m² for standard 200×50 mm bricks). All values must be > 0.
