Question

The width of a strand of fiber is 19.2 micrometers. If 1500 strands are adhered side by side, how wide would the resulting fabric be if measured in centimeters?

Answer 1

Thank you for posting your question here at brainly. Below is the solution:

19.2 microns x 1500 strands = X cm 
1.92x10^^-5 m x 1.5 x 10^^3 = 2.88x 10^^-2 m = 2.88 cm 


Convert to scientific notation and then the units work out easily.

Answer 2

Answer:

The fabric would be 2.88 cm

Explanation:

1- getting width of fabric in micrometers:

We are given that a single strand is 19.2 micrometers and that the fabric would be formed by connecting 1500 strand.

This means that:

width of fabric = 19.2 * 1500 = 28800 micrometers

2- getting the width in cm:

The basics of conversions states that:

1 micrometer = 0.0001 cm

To convert 28800 micrometers to cm, all you have to do is cross multiplication as follows:

1 micrometer ....................> 0.0001 centimeters

28800 micrometers .......> ?? centimeters

width of fabric = $\frac{28800 * 0.0001}{1}$ = 2.88 cm

Hope this helps :)
