Question

If a 20.0mL test tube measures 15.0cm, what is the length in meters?

Answer 1

Answer : The length of the test tube in meter is 0.15 meter

Explanation :

The conversion used for length from centimeter to meter is:

1 cm = 0.01 m

As we are given the length of the test tube is, 15.0 cm. Now we have to determine the length of the test tube in meter.

As, 1 cm of length of the test tube = 0.01 meter

So, 15.0 cm of length of the test tube = $\frac{15.0cm}{1cm}\times 0.01m=0.15m$

Therefore, the length of the test tube in meter is 0.15 meter

Answer 2

15.0 cm(1 m/100 cm) = 0.150 m Always include your units so you can tell what your final units will be.
