Answer: 44,000 square feet.
Step-by-step explanation:
If we are assuming use of the direct method, we can find out how the building maintenance cost will be allocated using the following formula,
Building Maintenance cost square feet allocation = Square Footage of Machining + Square Footage of Assembly
Slotting in the figures we have,
= 18,000 + 26,000
= 44,000 square feet.
The Building Maintenance cost will be allocated over 44,000 square feet.
