Final answer:
To reach the Moon, approximately 2.85717924528 × 1011 dimes, stacked one on top of the other, would be needed, given the distance of 239,000 miles and the thickness of a dime at 0.053 inches.
Step-by-step explanation:
To calculate the number of dimes needed to stack from the Earth to the Moon, we must first determine the total distance in inches. The distance from the moon to the earth is about 239,000 miles, and since a mile is 63,360 inches, we multiply 239,000 by 63,360 to get 15,143,040,000 inches. Now, a dime has a thickness of approximately 0.053 inches. So to find out how many dimes we would need, we divide the total inches by the thickness of a dime which is 15,143,040,000 inches ÷ 0.053 inches/dime, resulting in roughly 285,717,924,528 dimes. To write this in scientific notation, we express this number as 2.85717924528 × 1011 dimes.
