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

Answer 1

To convert meters to millimeters, we multiply the number of meters by 1,000.

The width of the sticky note is 1.25 × 10^−8 meters. Multiplying this by 1,000 gives us:

1.25 × 10^−8 meters × 1,000 = 1.25 × 10^−8 × 10^3 = 1.25 × 10^−5 millimeters.

The length of the sticky note is 2.5 × 10^−6 meters. Multiplying this by 1,000 gives us:

2.5 × 10^−6 meters × 1,000 = 2.5 × 10^−6 × 10^3 = 2.5 × 10^−3 millimeters.

Therefore, the dimensions of the sticky note in millimeters are 1.25 × 10^−5 millimeters wide by 2.5 × 10^−3 millimeters long.
