Kendra finds the dimensions of a sticky note. She uses a meter stick to determine that the dimensions are 1.25×10−8 meters wide by 2.5×10−6 meters long. Use scientific notation to write the dimensions in millimeters.

Question

Note: 1 meter is equal to 1,000 millimeters.

Answer 1

To convert the width from meters to millimeters, we multiply by 1,000:

1.25 × 10^-8 meters * 1,000 millimeters/meter = 1.25 × 10^-5 millimeters

To convert the length from meters to millimeters, we multiply by 1,000:

2.5 × 10^-6 meters * 1,000 millimeters/meter = 2.5 × 10^-3 millimeters

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