A tape dispenser holds 1.14 × 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.
To find the total area of the tape, we need to multiply the length of the tape (1.14 × 10^4 mm) by the width of the tape (12.7 mm).
1.14 × 10^4 mm multiplied by 12.7 mm is equal to:
1.14 × 12.7 × 10^4 mm²
To multiply these numbers, we can multiply 1.14 and 12.7 first, and then multiply the result by 10^4. The product of 1.14 and 12.7 is 14.478.
Therefore, 1.14 × 10^4 mm multiplied by 12.7 mm is equal to 14.478 × 10^4 mm².
In scientific notation, this is written as 1.4478 × 10^5 mm².
