Planning & EstimatingCâu 604 / 700
An excavation is 20 ft by 30 ft and 5 ft deep. After digging, the soil swells 25 percent for hauling. APPROXIMATELY how many loose cubic yards must be hauled away?
a.111 cubic yards
b.3,000 cubic yards
c.125 cubic yards
d.139 cubic yards
Giải thích
Bank volume = 20 x 30 x 5 = 3,000 cubic feet. Divide by 27: 3,000 / 27 = 111.1 bank cubic yards. Apply 25 percent swell: 111.1 x 1.25 = 138.9, about 139 loose cubic yards (d). Option (a) ignores swell. Option (b) leaves cubic feet without dividing by 27. Option (c) applies only about a 12 percent swell.
