Bank excavation is 1,035 cubic yards and soil swells 20 percent for hauling. What loose volume is hauled?
Correct Answer
B) 1,242 cy
Loose volume is 1,035 x 1.20 = 1,242 cy.
Why This Is the Correct Answer
Loose volume is 1,035 x 1.20 = 1,242 cy.
Why the Other Options Are Wrong
Option A: 1,104 cy
earthwork swell volume, choice a: 1,104 cy implies about 6.67 percent swell on 1,035.
Option C: 1,200 cy
earthwork swell volume, choice c: 1,200 cy implies about 15.94 percent swell on 1,035.
Option D: 1,328 cy
earthwork swell volume, choice d: 1,328 cy implies about 28.31 percent swell on 1,035.
Memory Technique
Keep a release point beside earthwork swell volume: if one number is skipped, the option drifts away from 1,242 cy.
Reference Hint
Open Pipe and Excavation Contracting, 2011; use by topic index - earthwork volume / swell / shrink to confirm that Loose volume is 1,035 x 1.20 = 1,242 cy.
