1.4478×104 mm2
1.4478 times 10 superscript 4 baseline mm squared
1.4478×105 mm2
1.4478 times 10 superscript 5 baseline mm squared
14.478×105 mm2
14.478 times 10 superscript 5 baseline mm squared
14.478×104 mm2
To find the total area in square millimeters of tape, you need to multiply the two numbers: 1.14×10^4 mm and 12.7 mm. The product would be:
1.14×10^4 mm × 12.7 mm = 14.478×10^4 mm^2
Therefore, the correct answer is: 14.478×10^4 mm^2
A sugar cube has a volume of about 4.9 ml. What is the total volume in milliliters of 1.5×106 sugar cubes?(1 point)

To find the total volume in milliliters of 1.5×10^6 sugar cubes, you need to multiply the volume of one sugar cube (4.9 ml) by the number of sugar cubes (1.5×10^6). The product would be:
4.9 ml × 1.5×10^6 = 7.35×10^6 ml
Therefore, the correct answer is: 7.35×10^6 ml.

To multiply 0.75 by 2.8×10^-5, you simply multiply the two numbers:
0.75 × 2.8×10^-5 = 2.1×10^-5
Therefore, the correct answer is: 2.1 × 10^-5.
