(Questions)
What is the difference in height of Mont St. Helens?

Before the eruption, how many kilometers high was Mount St. Helens?

Which of the following is eguals to 2 meters?
(A) 200mm (B) 20cm (C) 200km

Explain how you would convert 4m to millimeters.

Answer 1

1. The difference in height is 400 meters because difference = subtract.

2. Mount St. Helens was 2.95 cause 1 meter = 0.001 killometer, so 0.001 x 2950 = 2.95.

3. None of them are right...

4. You would convert 4m into millimeters by doing 1000 x 4 because 1 meters = 1000 millimeters. The answer will be 4000 millimeters
