 Each crane can perform 30 lifts per day with a 1.75 cubic yard bucket. For 3 cranes over 5 days: Concrete volume per day=3 cranes×30 lifts/crane/day×1.75 CY/lift.\text{Concrete volume per day} = 3 \text{ cranes} \times 30 \text{ lifts/crane/day} \times 1.75 \text{ CY/lift}.Concrete volume per day=3 cranes×30 lifts/crane/day×1.75 CY/lift. Daily volume=157.5 CY/day.\text{Daily volume} = 157.5 \text{ CY/day}.Daily volume=157.5 CY/day. Over 5 days: Total volume=157.5×5=306 CY.\text{Total volume} = 157.5 \times 5 = 306 \text{ CY}.Total volume=157.5×5=306 CY.
