I’m leaning towards option D, 306 CY sounds right!

Wait, are we sure about those bucket sizes?

5 days of that means 450 lifts!

Each crane can do 30 lifts a day, so that's 90 lifts total.

If each crane does 30 lifts a day, then over 5 days, that’s 150 lifts per crane. I just need to remember how to multiply that by the bucket size correctly.

I think the total volume is based on the number of lifts and the bucket size, but I’m a bit confused about the conversion between cubic yards and cubic meters.

This seems similar to a practice question we did on crane operations, but I can't recall the exact formula we used.

I remember we calculated crane capacities in class, but I'm not sure how to factor in the lifts per day.

This seems doable, just need to make sure I account for all the variables and do the math correctly. Gotta stay focused on this one.

Okay, I think I've got the key info - 3 cranes, 30 lifts per day per crane, 1.75 CY or 1.34 CM buckets. Time to start crunching the numbers.

Hmm, not sure I fully understand all the units and constraints here. Might need to re-read the question a few times.

You know, if I was the crane operator, I'd be more concerned about not knocking over the whole construction site with my mad skills. Just sayin'.

I just hope they don't trick us with that 1.75 CY or 1.34 CM thing. That's going to be the key to solving this problem, I bet.
