To find the mechanical advantage of the wedge, you can use the formula given:
\[
\text{Mechanical Advantage} = \frac{\text{length of sloped side}}{\text{width of wedge}}
\]
In this case, the length of the sloped side is 16 cm and the width of the wedge is 8 cm. Plugging these values into the formula:
\[
\text{Mechanical Advantage} = \frac{16 \text{ cm}}{8 \text{ cm}} = 2
\]
So, the mechanical advantage of the wedge is 2.0.
The correct answer is **D) 2.0**.
