Final answer:
The height of a stack of 1 million dimes is 1.35 x 10^3 meters.
Step-by-step explanation:
To find the height of a stack of 1 million dimes, we need to multiply the thickness of one dime by 1 million. The thickness of one dime is given as 1.35 x 10-3 meter. Multiplying this by 1 million gives:
1.35 x 10-3 meter x 1 x 106 = 1.35 x 103 meters
Therefore, the height of a stack of 1 million dimes is 1.35 x 103 meters.
