What is the total office area required if each office is 120 sf?

To determine the total office area required based on individual office sizes, it is essential to multiply the area of one office by the total number of offices. If each office measures 120 square feet and the total number of offices needed is 5, the calculation would be:

120 square feet (area of one office) multiplied by 5 (number of offices) equals 600 square feet.

This confirms that option B, which states the total office area is 600 square feet, is correct. Knowing the size of each office and the number needed is crucial for accurate calculations in architectural planning and space allocation.
