What is the volume in cubic yards of material removed from a trench measuring 120 ft by 4 ft with a removal depth of 6 inches?

Explanation:
Volume is found by multiplying length, width, and depth, then converting from cubic feet to cubic yards. The trench is 120 ft long and 4 ft wide, with depth 6 inches (0.5 ft). So the volume in cubic feet is 120 × 4 × 0.5 = 240 ft³. Since 1 cubic yard = 27 cubic feet, the volume in cubic yards is 240 ÷ 27 ≈ 8.888..., which rounds to 8.9 cubic yards.
