Answer options:

  • 27 LCM ✅ 35.1 LCM
  • 20.7 LCM
  • 30.8 LCM

Correct answer: 35.1 LCM

Explanation: First, calculate the total bank cubic volume (BCM): 12 buckets * 2.25 BCM/bucket = 27 BCM. Then, convert to loose cubic metres (LCM) by applying the swell factor: 27 BCM * (1 + 0.30) = 27 BCM * 1.30 = 35.1 LCM. (Reference: OPSWA HEO Curriculum, Earthmoving Math Module).
