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.
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
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.
To find the total area in square millimeters of tape, you need to multiply the length and the width of the tape.
The given length is 1.14 x 10^4 mm, and the width is 12.7 mm.
To multiply these two numbers, you can follow these steps:
1. Multiply the numerical parts: 1.14 x 12.7 = 14.478
2. Add the exponents: 10^4 x 10^0 = 10^4
Combining these two results, the total area in square millimeters of tape is 14.478 x 10^4 mm^2.
Therefore, the correct answer is option 3: 14.478 x 10^4 mm^2.
To find the total area in square millimeters of 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
Therefore, the correct answer is 1.4478 x 10^5 mm^2. Option 1 is the correct answer.
