The formula to calculate the total square footage of subflooring (SF) is:
\[ \text{SF} = L \times W \]
Where:
A subfloor is the foundational layer of flooring in a building, typically made of plywood or concrete, that provides support for the visible flooring material such as hardwood, carpet, or tiles. It is a structural component that is directly attached to the floor joists, ensuring stability and levelness. The subfloor also acts as a barrier against moisture from the ground.
Let's assume the following values:
Using the formula to calculate the total square footage of subflooring:
\[ \text{SF} = 20 \times 15 = 300 \text{ sq ft} \]
The total square footage of subflooring needed is 300 sq ft.
