A cut and fill operation requires moving 2,400 cubic yards of soil. The soil has a swell factor of 25% when excavated and a shrinkage factor of 8% when compacted. How many cubic yards must be excavated to achieve 2,400 cubic yards of compacted fill?
Correct Answer
A) 2,609 cubic yards
Required in-place volume = 2,400 ÷ (1 - 0.08) = 2,400 ÷ 0.92 = 2,609 cubic yards of original soil must be excavated.
Why This Is the Correct Answer
Required in-place volume = 2,400 ÷ (1 - 0.08) = 2,400 ÷ 0.92 = 2,609 cubic yards of original soil must be excavated.
