Excavation is to be made for a reservoir measuring 20 m long, 12 m wide at the bottom and 2 m deep. The side-slopes are to be 1:1 and the top to be flush with the ground which is level in the vicinity as per prismoidal formula, the volume of excavation will be:
610.33 m3
618.66 m3
625.00 m3
633.66 m3
618.66 m3
For the calculation of volume by prismoidal formula, consider three levels at common interval 1m. The areas of these levels at the bottom, mid and top are as follows-
