PLEASE ANSWER I NEED THE ANSWERS!!!
yKpoI14uk [10]

Answer:

1: 7.8 cm

2: .7 cm

3: 5.55 cm

For the other questions, you have to use a ruler yourself and measure using cm. :)

1 cm = 10 millimeter. To convert, just add a 0 to the end of cm to find the mm (or move the decimal one place to the right.)

For example, 2.6 cm = 26 mm / 5 cm = 50 mm. Hope this helps!
