Answer: 10400 unfavorable
Step-by-step explanation:
Firstly, we should note that the fixed overhead volume variance is the difference between the standard fixed overhead for actual output and the budgeted fixed overhead.
Budgeted fixed overhead = 780000
The standard fixed overhead for the actual output will be:
= Actual output × Number of hour per unit × the standard fixed overhead rate
= 14800 × 4 × 13
= 769,600
Then, the fixed overhead volume variance will be:
= 769600 - 780000
= 10400 Unfavorable
