Core TradesCâu 165 / 700
A contractor must haul away 100 bank cubic yards (in-place volume) of soil that has a swell factor of 25%. What loose volume must the trucks carry?
a.112 loose cubic yards
b.125 loose cubic yards
c.100 loose cubic yards
d.75 loose cubic yards
Giải thích
Excavating loosens soil so it occupies more space; a 25% swell means the loose volume is the bank volume times 1.25: 100 x 1.25 = 125 loose cubic yards. 100 ignores swell, 75 wrongly reduces the volume, and 112 uses about 12% instead of 25%.
