An excavation for a basement measures 30 ft long, 20 ft wide, and 3 ft deep. How many bank cubic yards of soil are removed?
a.55.6 cubic yards
b.72 cubic yards
c.88.9 cubic yards
d.66.7 cubic yards
Explanation
Volume = 30 x 20 x 3 = 1,800 cubic feet. Divide by 27 to convert to cubic yards: 1,800 / 27 = 66.7 bank cubic yards. 72 comes from dividing by 25, and the other values from arithmetic errors. This is the in-place (bank) volume before any swell.
