Final answer:
To find the surface area of the ramp, we need to calculate the area of each face and then add them together. However, since the width of the ramp is not mentioned in the given information, we cannot determine the surface area.
Step-by-step explanation:
To find the surface area of the ramp, we need to calculate the area of each face and then add them together.
Since the ramp is made up of a single board, we can assume it is rectangular. The length of the ramp is 3 meters and the width can be measured by the distance from the bottom to the top of the ramp. The width is not mentioned in the given information, so we cannot calculate it.
Therefore, we cannot determine the surface area of the ramp without knowing the width.
