Calculates the volume of concrete or mortar needed to fill hollow concrete blocks, based on block dimensions and the number of blocks.
Start with your values, or try a preset.
Enter Block Length (inches), Block Height (inches), Block Width (inches), Block Wall Thickness (inches), and Number of Blocks in the units shown.
Read Hollow Volume per Block (cubic inches), Block Volume (cubic inches), Concrete/Mortar Volume per Block (cubic inches), Total Concrete/Mortar Volume (cubic inches), and Total Concrete/Mortar Volume (cubic feet) in the results panel. Results update as you change the inputs.
Choose a preset to load an example, then adjust the values for your situation.
