How many bricks should I buy?

Excuse me, I'm considering investing in bricks for a potential construction project, but I'm unsure of the quantity I should purchase. Could you please provide some guidance on how to determine the appropriate number of bricks to buy? Are there any factors I should consider, such as the size of the project, the type of bricks, or the availability in the market? I'm looking for a comprehensive approach to ensure that I make an informed decision and avoid any potential oversupply or shortages.
