🚜Volume Estimation Challenge: Material Moved
🎯 Objective
Calculate how much material is moved:
- Per bucket/pass
- Per hour of operation
📏 Key Formula
Volume per pass = Bucket Capacity × Fill Factor
Volume per hour = Volume per pass × Cycles per hour

🧩 Game Round 1: Per Pass Calculation
Problem 1
An excavator has:
- Bucket capacity: 1.5 m³
- Material: gravel (0.90 fill)
👉 What is the volume moved per pass?
Problem 2
A loader has:
- Bucket capacity: 3.0 m³
- Material: wet soil (0.70 fill)
👉 Volume moved per pass?
Problem 3
A backhoe moves:
- Bucket capacity: 0.8 m³
- Material: clay (0.80 fill)
👉 Volume moved per pass?
⏱️ Game Round 2: Per Hour Production
Problem 4
Excavator cycles: 120 cycles/hour
From Problem 1 result
👉 What is the total hourly volume?
Problem 5
Loader cycles: 75 cycles/hour
From Problem 2 result
👉 Total hourly volume?
Problem 6
Backhoe cycles: 90 cycles/hour
From Problem 3 result
👉 Total hourly volume?
🧠 Bonus Round (Advanced)
Problem 7
A bulldozer pushes:
- Blade capacity: 5 m³
- Fill factor: 0.85
- Cycles: 60 per hour
👉 Total volume per hour?
Problem 8
A haul truck carries:
- Capacity: 20 m³ per load
- Loads per hour: 8
- Efficiency factor: 0.95
