Aneli [31]

Answer:

0.0008 m

Explanation:

We are given that 0.080 cm

We have to convert 0.080 cm into meter

To find the value of 0.080 cm in meter we are using unitary method

We know that

100 cm =1 m

1 cm =\frac{1}{100} m

Therefore, 0.080 cm =\frac{1}{100}\times 0.080 m

0.080 cm =\frac{1}{100}\times \frac{80}{1000}m

0.080 cm =\frac{8}{10000}m

0.08cm=0.0008 m

Hence, the value of 0.080 cm is equal to 0.0008 meter .
