What is the formula for treating an area of soil to be covered by a slab?

1. Length X Depth

2. Length X Width

3. Width X Depth

4. Length + Width

The correct answer is: Length X Width

The formula for treating an area of soil that will be covered by a slab is based on calculating the area of a rectangle. In this context, the most relevant factors are the length and width of the area to be covered. By multiplying the length by the width, you obtain the total area required for the slab, which tells you how much soil needs to be treated. This makes length and width the essential measurements for understanding the overall dimensions of the area in question. Using this formula ensures that you account for the entire expanse that the slab will cover, allowing for accurate treatment and preparation of the soil beneath it. Other options, such as length times depth or width times depth, do not accurately capture the area. Instead, they could imply a volume calculation, which is not applicable when addressing a flat surface like a slab. Adding length and width, on the other hand, does not yield a relevant measurement for area. Thus, focusing on the length and width directly leads to the correct calculation for the area to be covered by the slab.
