What is the formula to calculate the volume of bricks needed for a wall?

• Number of bricks = (Length of wall x Height of wall x Thickness of wall) / (Width of brick x Height of brick)

• Number of bricks = (Length of wall x Width of wall x Height of wall) / (Length of brick x Height of brick)

• Number of bricks = (Length of wall x Height of wall) / (Length of brick x Width of brick)

• Number of bricks = (Length of wall x Height of wall x Thickness of wall) / (Length of brick x Width of brick x Height of brick)

If a wall is 10m long, 3m high, and 0.1m thick, how many bricks are needed?
