Final answer:
The moisture content of a piece of wood is calculated based on its wet and dry weight. By applying the formula (Wet Weight - Dry Weight) / Dry Weight) × 100, we determine that the moisture content is 33%. Therefore, the answer is D. 33%.
Step-by-step explanation:
The moisture content of a piece of wood can be calculated using the weight of the wood when it's wet (just after being cut) and its weight after it has been dried. To find the moisture content percentage, we subtract the dry weight from the wet weight, divide the result by the dry weight, and then multiply by 100 to get the percentage.
The formula looks like this: Moisture Content (%) = ((Wet Weight - Dry Weight) / Dry Weight) × 100
Applying the formula to the weights provided: Moisture Content (%) = ((48 lbs - 36 lbs) / 36 lbs) × 100
This gives us: Moisture Content (%) = (12/36) × 100 = 33%
Hence, the correct answer to the question is D. 33%.
