Formula used

Blocks needed = Net wall area ÷ block face area.

Blocks to buy = blocks needed × (1 + waste %) and rounded up.

Total cost = block cost + mortar cost + labor cost + rebar/grout allowance + cap row cost + delivery/misc cost.

All wall dimensions are converted to feet for the wall area calculation.
