Formula and method
This calculator computes Blocks needed directly in your browser without sending data to an external server.
Mathematical formula
- Blocks needed:
Math.ceil((wallLengthFt × 12) ÷ blockLengthIn) × Math.ceil((wallHeightFt × 12) ÷ blockHeightIn)
Variables and parameters
- Wall length (wallLengthFt): default value 30 ft.
- Wall height (wallHeightFt): default value 3 ft.
- Block height (blockHeightIn): default value 6 in.
- Block length (blockLengthIn): default value 18 in.
