Using a 1.

 The column volume is 2,000 cubic feet (56.64 cubic meters), and each lift using a 1.75 cubic yard bucket corresponds to: Lifts required=Column volume (cubic yards)Bucket capacity (cubic yards)\text{Lifts required} = \frac{\text{Column volume (cubic yards)}}{\text{Bucket capacity (cubic yards)}} Lifts required=Bucket capacity (cubic yards)Column volume (cubic yards)​ Convert 56.64 cubic meters to cubic yards: 56.64×1.308=74.1456.64 \times 1.308 = 74.1456.64×1.308=74.14. Lifts required=74.141.75≈133 lifts.\text{Lifts required} = \frac{74.14}{1.75} \approx 133 \text{ lifts}.Lifts required=1.7574.14​≈133 lifts.
