A thin copper wire has a length L at . When heated to , its length increases by . If a thin copper plate of dimension L × 3L is heated through the same range of temperature, its surface area gets increased by x %. Fill value of 10x.

Answer:
2
Solution:

Linear increase is 0.1%. Area increase is approximately twice this, 0.2%.

Thus x=0.2 and 10x=2.
