Concrete Block Fill Formula
Volume per Block = Inside Width × Inside Thickness × Height
Total Volume = Volume per Block × Number of Blocks
Volume with Spillage = Total Volume × (1 + Spillage%/100)
Total Volume = Volume per Block × Number of Blocks
Volume with Spillage = Total Volume × (1 + Spillage%/100)
Note: Measure the inside dimensions of the block cavities. Subtract shell and web thicknesses from the overall block dimensions to get accurate inside measurements. It's recommended to add 5-10% extra concrete to account for spillage and minor measurement variations.
