Question 1045221: In alot 12.2 m long and 6.5 m wide, a cellar is to be dug. The cellar is to be 5.5 m long, 3.6 m wide and 2.4 deep. The earth removed is to be used to fill the surrounding yard. What depth of fill can be made? (this is rectangular parallelepiped problem) Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! The area of the lot is 12.2 * 6.5 = 79.3 square meters
:
The area of the base of the cellar is 5.5 * 3.6 = 19.8 square meters
:
The volume of the cellar is 19.8 * 2.4 = 47.52 cubic meters
:
Note that the volume of a rectangular parallelpiped (the cellar in this case) is
the area of the base times the height(depth)
:
The area to be covered is 79.3 - 19.8 = 59.5 square meters
:
*********************************************************************************
Depth of fill is 47.52 cubic meters / 59.5 square meters = 0.79 approx 0.8 meters
