To calculate the number of concrete blocks you'll need for a project (like building a wall), follow these steps:
Area = Height × Length
Concrete blocks come in different sizes. A common standard block size is 16 inches long by 8 inches high (16" x 8"). However, some blocks may be different sizes, so check the specific dimensions for your project.
If the block size is 16" x 8" (or 1.33' x 0.67'), the area of one block is:
Area of 1 block = 1.33′ × 0.67′ = 0.89 ft²
Now, divide the total area of the wall by the area of one block:
