Calculate the volume of top soil to be removed in cubic yards if within a 50ft X 50ft
square requires an additional lowering of pad by 0.1ft?
9.26 cubic yards
(50x50x0.1)/(27)
1 cubic yard = 27 cubic feet

Match the conditioning effect with its description.
When a distance is to be laid out with a chain that is too short, the point will be
set closer than it should be.
When a distance between two points is measured with a chain that is too short,
the distance that is recorded will be larger or more than the actual length of the
line.
When a distance is laid out with a chain that is too long, the point will be set
farther than it should be.
When a distance between two points is measured with a chain that is too long,
the distance that is recorded will be smaller or less than the actual length of the
line.
