Step 1: Find linear feet (length + width).

Step 2: Multiply by 12 = inches

Step 3: Divide inches by 18 or 16 (block sizes) =
number of blocks per course

Step 4: Multiply the number of blocks per course
by the number of courses = number of block.

**Note:12 courses for basements

35 blocks per 1 bag of mortar mix (Type S)

9 bags of mortar mix / 1 yard of mortar sand
