To convert the width to millimeters, we need to multiply it by 1,000.
1.25 × 10^-8 × 1,000 = 1.25 × 10^-5 millimeters.

To convert the length to millimeters, we also need to multiply it by 1,000.
2.5 × 10^-6 × 1,000 = 2.5 × 10^-3 millimeters.

The dimensions of the sticky note in millimeters are 1.25 × 10^-5 mm wide by 2.5 × 10^-3 mm long.

To find the total number of seconds the playlist will play, we need to multiply the number of songs by the average song length in minutes and then convert the result to seconds.

1,900 songs * 3.5 minutes = 6,650 minutes

To convert minutes to seconds, we need to multiply by 60.

6,650 minutes * 60 seconds = 399,000 seconds

Therefore, the total number of seconds the playlist will play is 399,000 seconds.
