To calculate the total resource requirement for the project, multiply the hours per day by the time (days) for each activity and sum them up: - A: $4 \times 6 = 24$ hours- B: $4 \times 11 = 44$ hours- C: $5 \times 5 = 25$ hours- D: $4 \times 6 = 24$ hours- E: $4 \times 6 = 24$ hours- F: $6 \times 3 = 18$ hours- G: $3 \times 11 = 33$ hours- H: $3 \times 8 = 24$ hours- J: $3 \times 10 = 30$ hours- K: $6 \times 4 = 24$ hoursAdding these together gives a total of $24 + 44 + 25 + 24 + 24 + 18 + 33 + 24 + 30 + 24 = 270$ hours. However, since the worker is expected to devote half-time (four hours per day) to this project, and the calculation already assumes 4 hours per day for activities A, B, D, E, and F (which aligns with the worker's available time), the total hours calculated directly reflect the total resource requirement without needing to adjust for half-time work. Therefore, the initial calculation seems to have been misunderstood in the explanation process. Correctly adding the calculated hours for each activity should give the total resource requirement for the project. Let's correct the calculation:- A: $4 \times 6 = 24$ hours- B: $4 \times 11 = 44$ hours- C: $5 \times 5 = 25$ hours- D: $4 \times 6 = 24$ hours- E: $4 \times 6 = 24$ hours- F: $6 \times 3 = 18$ hours- G: $3 \times 11 = 33$ hours- H: $3 \times 8 = 24$ hours- J: $3 \times 10 = 30$ hours- K: $6 \times 4 = 24$ hoursThe correct total should be calculated based on the sum of hours needed for each activity, considering their respective durations and hours per day as listed. The mistake in the explanation was in the summation and interpretation of the half-time work condition. Given the provided options and the error in the initial explanation, the correct approach is to sum the hours as they are, assuming the table already accounts for the half-time work condition by specifying hours per day for each task. The correct sum should match one of the provided options accurately.
