Explanation:

Question 8

U.S. standard letter - size paper has dimensions of 8.5 inches by 11 inches. To convert inches to centimeters, we use the conversion factor \(1\) inch \( = 2.54\) centimeters. The length of letter - size paper is 11 inches. Converting 11 inches to centimeters: \(11\times2.54 = 27.94\) centimeters, which is closest to 29 centimeters among the given options. Options a (8 cm) and b (11 cm) are too small, and option d (300 cm) is way too large.

A U.S. nickel has a known weight. Through standard measurements and knowledge of U.S. coin weights, a nickel weighs approximately 5 grams. Option a (0.1 gram) is too light, option c (50 grams) and d (100 grams) are much heavier than the actual weight of a nickel.

Answer:

c. 29 centimeters
