A tape dispenser holds 1.14 x 10^4 mm of tape that is 12.7 mm wide. Multiply the two numbers to find the total area in square millimeters of tape. Write the product in scientific notation.

Question

1. 1.4478 x 10^5 mm2
2. 14.478 x 10^5 mm2
3. 14.478 x 10^4 mm2
4. 1.4478 x 10^4 mm2

Answer 1

To find the total area of the tape, you need to multiply the length of the tape (1.14 x 10^4 mm) by the width of the tape (12.7 mm):

1.14 x 10^4 mm * 12.7 mm = 1.4478 x 10^5 mm^2

The product written in scientific notation is 1.4478 x 10^5 mm^2, so the correct answer is 1. 1.4478 x 10^5 mm2.
