Final answer:
The upper bound of 187 correct to 3 significant figures is 190, and the lower bound is 180.
Explanation:
To find the upper and lower bounds of 187 correct to 3 significant figures, we need to round the number to the nearest hundredth. Since 187 has only 2 significant figures, we can round it to 190 to meet the 3 significant figures requirement. Therefore, the upper bound is 190.
To find the lower bound, we need to round the number to the nearest ten. Since 187 is in the range of 180-189, we can round it to 180 to meet the 3 significant figures requirement. Therefore, the lower bound is 180.
