About this result

This calculator gives geometric volume only (length × width × thickness, or π r² × height for columns). Cement, sand, aggregate and water quantities depend on the mix design and grade specified by your engineer, so they are not calculated here. Ask your supplier whether to order extra for wastage and spillage.
