To find the total area of tape, we need to multiply the length (1.14 × 10⁴ mm) by the width (12.7 mm).
1.14 × 10⁴ mm * 12.7 mm = 14.478 × 10⁴ mm²
Writing this in scientific notation, we can simplify 14.478 × 10⁴ mm² to 1.4478 × 10⁵ mm².
Therefore, the correct answer is A. 1.4478 × 10⁵ mm².
A tape dispenser holds 1.14 × 10⁴ 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.
A. 1.4478 × 10⁵ mm²
B. 14.478 × 10⁴ mm²
C. 1.4478 × 10⁴ mm²
D. 14.478 × 10⁵ mm²
