Estimate concrete volume for rectangular or circular columns, including multiple identical columns.

Core method:
Rectangular area = width × depth. Circular area = π × diameter² / 4. Volume = area × height × count.

Before you use the result: Check project drawings, supplier data and site conditions before ordering materials.
