摘要: One or more methods and apparatuses for determining a characteristic, such as volume, of an excavated void construction material are provided. The one may include excavating defined in material, interacting with the using device at least measurement thereof, manipulating to determine characteristic volume obtaining based on measurements obtained. apparatus configured interact surface therein respective thereof manipulate plurality so void.
