In the construction of a new building, a landscape architect determined that he had a plot 810 feet by 35 feet, to be filled to a depth of 6 inches with loam. how many cubic yards of loam would he require?

Given that the shape to be field with loam is is a cuboid, the volume of loam required to fill the space will be given by the formula:
volume=length*width*height
where;
length=810 ft
width=35 ft
height=6 inches
thus, the volume will be:
Volume=810*35*6=170,100 cubic feet
The answer is 170,100 ft^3
