Core TradesQuestion 211 of 700
A trench measures 90 ft long, 3 ft wide, and 4 ft deep. How many bank (in-place) cubic yards of soil must be excavated?
a.20 cubic yards
b.30 cubic yards
c.40 cubic yards
d.120 cubic yards
Explanation
Volume = 90 x 3 x 4 = 1,080 cubic feet; 1,080 / 27 = 40 cubic yards. The 20 and 30 answers understate the cross-section, and 120 leaves the result in cubic feet without dividing by 27.
