Answer 1

ANSWER :
0 Depth below the ground= 3oft consider width of the project = 150 ft quantity required for excavation bxdxh. = 30X 150X120 3 = 540000 43 Now, filling the excavation work of 54000 fts with quantity of clay (or) Marum of same quantity in 540000 Ft Now Let us consider I vehicle capacity of claycor) Marum as 150 ft² 31 Now , Number of vehicles trips 540000 150 required = 3600 trips Now, 3600 =4.5 work for 800 Number of vehicles trips required for a day 800 days er cavation' work is = 5 vehicles/day

Now, I excavator can excavate 250 ft 3 in one day. Now . Number of excavator gequired - 540000 250 = 2160 Now, to complete excavation in 800 days then 21600 800 =2.7. Excavators work = 2,7 No. of ex cavation required per day w 3 excavators ... We need 3 number of excavatorfor ercavation box 800 days work of 540000 ft 3.
