Excavation, removal and dumping of earth are one of the frequent works in engineering survey. The junctions of the square grid shown below were levelled to determine the volume of excavation necessary in the construction of basement floor. The reduced levels of the grid points are as shown. The grid distance between points are 20m and the required formation level is to be at 95.0 m. Determine the volume to be cut or fill using Grid formula
