What is the square footage of a 4ft x 6ft space?

To determine the square footage of a space, you multiply its length by its width. In this case, the length is 4 feet and the width is 6 feet. So, you perform the multiplication:

4 feet (length) x 6 feet (width) = 24 square feet.

This calculation shows that the correct answer reflects the area of the given space, making it 24 square feet. Understanding how to calculate square footage is an essential skill in HVAC and many other fields, as it helps in assessing the size of areas for equipment installation and space planning.
