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.
To find the total area in square millimeters of tape, we need to multiply the length and the width.
Length: 1.14 x 10^4 mm
Width: 12.7 mm
Multiply the coefficients: 1.14 x 12.7 = 14.478
Add the exponents: 4 + 0 = 4
Therefore, the total area in square millimeters of tape is 14.478 x 10^4 mm^2. In scientific notation, this can be written as 1.4478 x 10^5 mm^2.
Length: 1.14 x 10^4 mm
Width: 12.7 mm
Multiply the coefficients: 1.14 x 12.7 = 14.478
Add the exponents: 4 + 0 = 4
Therefore, the total area in square millimeters of tape is 14.478 x 10^4 mm^2. In scientific notation, this can be written as 1.4478 x 10^5 mm^2.

To find the total volume in milliliters of 1.5 × 10^6 sugar cubes, we need to multiply the volume of one sugar cube by the total number of sugar cubes.
Volume of one sugar cube: 4.9 ml
Total number of sugar cubes: 1.5 × 10^6
Multiply the coefficients: 4.9 × 1.5 = 7.35
Add the exponents: 0 + 6 = 6
Therefore, the total volume in milliliters of 1.5 × 10^6 sugar cubes is 7.35 × 10^6 ml.
